Weights and Measures
wats me'-zhur : The system of weights and measures in use among the Hebrews was derived from Babylonia and Egypt, especially from the former. The influence of these countries upon Palestine has long been recognized, but archaeological investigations in recent years have shown that the civilization of Babylonia impressed itself upon Syria and Palestine more profoundly in early times than did that of Egypt. The evidence of this has been most clearly shown by the discovery of the Tell el-Amarna Letters, which reveal the fact that the official correspondence between the Egyptian kings and their vassals in these lands was carried on in the language of Babylonia long after its political influence had been supplanted by that of Egypt. It is natural, then, that we should look to Babylonia for the origin of such important elements of civilization as a system of weights and measures.
1. Linear Measures:
It was quite natural that men should have found a standard for linear measures in the parts of the human body, and we find the cubit, originally the length of the forearm, taken as the standard, and the span, the palm and the digit, or finger-breadth, associated with it in linear measurement. They do not seem to have employed the foot, though it is represented in the two-thirds of the cubit, which was used by the Babylonians in the manufacture of building-brick.
This system, though adequate enough for man in the earliest times, was not so for an advanced stage of civilization, such as the Babylonians reached before the days of Abraham, and we find that they had introduced a far more accurate and scientific system (see CUBIT). They seem to have employed, however, two cubits, of different lengths, one for commercial purposes and one for building. We have no undoubted examples of either, but judging by the dimensions of their square building-bricks, which are regarded as being two-thirds of a cubit on a side, we judge the latter to have been of about 19 or 20 inches. Now we learn from investigations in Egypt that a similar cubit was employed there, being of from 20.6 to 20.77 inches, and it can hardly be doubted that the Hebrews were familiar with this cubit, but that in more common use was certainly shorter. We have no certain means of determining the length of the ordinary cubit among the Hebrews, but there are two ways by which we may approximate its value. The Siloam Inscription states that the tunnel in which it was found was 1,200 cubits long. The actual length has been found to be about 1,707 feet, which would give a cubit of about 17.1 in. (see PEFS , 1902, 179). Of course the given length may be a round number, but it gives a close approximation.
Again, the Mishna states that the height of a man is 4 cubits, which we may thus regard as the average stature of a Jew in former times. By reference to Jewish tombs we find that they were of a length to give a cubit of something over 17 inches, supposing the stature to be as above, which approximates very closely to the cubit of the Siloam tunnel. The consensus of opinion at the present day inclines toward a cubit of 17.6 inches for commercial purposes and one of about 20 inches for building. This custom of having two standards is illustrated by the practice in Syria today, where the builder's measure, or dra', is about 2 inches longer than the commercial.
Of multiples of the cubit we have the measuring-reed of 6 long cubits, which consisted of a cubit and a hand-breadth each (Eze 40:5), or about 10 feet. Another measure was the Sabbath day's journey, which was reckoned at 2,000 cubits, or about 1,000 yards. The measuring-line was used also, but whether it had a fixed length we do not know.
In the New Testament we have the fathom (orguia), about 6 feet, and the furlong (stadion), 600 Greek feet or 606 3/4 English feet, which is somewhat less than one-eighth of a mile. The mile (milion) was 5,000 Roman feet, or 4,854 English feet, somewhat less than the English mile.
2. Measures of Capacity:
Regarding the absolute value of the measures of capacity among the Hebrews there is rather more uncertainty than there is concerning those of length and weight, since no examples of the former have come down to us; but their relative value is known. Sir Charles Warren considers them to have been derived from the measures of length by cubing the cubit and its divisions, as also in the case of weight. We learn from Eze 45:11 that the bath and ephah were equivalent, and he (Warren) estimates the capacity of these as that of 1/30 of the cubit cubed, or about 2,333.3 cubic inches, which would correspond to about 9 gallons English measure. Assuming this as the standard, we get the following tables for liquid and dry measure: Ce'ah and lethekh, in the above, occur in the Hebrew text, but only in the margin of the English. It will be noticed that the prevailing element in these tables is the duodecimal which corresponds to the sexagesimal of the Babylonian system, but it will be seen that in the case of weights there was a tendency on the part of the Hebrews to employ the decimal system, making the maneh 50 shekels instead of 60, and the talent 3,000 instead of 3,600, of the Babylonian, so here we see the same tendency in making the `omer the tenth of the 'ephah and the 'ephah the tenth of the chomer or kor.
Weights were probably based by the ancients upon grains of wheat or barley, but the Egyptians and Babylonians early adopted a more scientific method. Sir Charles Warren thinks that they took the cubes of the measures of length and ascertained how many grains of barley corresponded to the quantity of water these cubes would contain. Thus, he infers that the Egyptians fixed the weight of a cubic inch of rain water at 220 grains, and the Babylonians at 222 2/9. Taking the cubic palm at 25,928 cubic inches, the weight of that quantity of water would be 5,760 ancient grains. The talent he regards as the weight of 2/3 of a cubit cubed, which would be equal to 101,6 cubic palms, but assumes that for convenience it was taken at 100, the weight being 576,000 grains, deriving from this the maneh (1/60 of the talent) of 9,600 grains, and a shekel (1/50 of the maneh) 192 grains. But we have evidence that the Hebrew shekel differed from this and that they used different shekels at different periods. The shekel derived from Babylonia had a double standard: the light of 160 grains, or 1/3600 of the talent; and the heavy of just double this, of 320 grains. The former seems to have been used before the captivity and the latter after. The Babylonian system was sexagesimal, i.e. 60 shekels went to the maneh and 60 manehs to the talent, but the Hebrews reckoned only 50 shekels to the maneh, as appears from Ex 38:25-26, where it is stated that the amount of silver collected from 603,550 males was 100 talents and Ex 1:1-22,775 shekels, and, as each contributed a half-shekel, the whole amount must have been 301,775. Deducting the Ex 1:1-22,775 shekels mentioned besides the 100 talents, we have 300,000 or Ex 3:1-22,000 to the talent, and, as there were 60 manehs in the talent, there were 50 shekels to each maneh. When the Hebrews adopted this system we do not know, but it was in vogue at a very early date.
The shekel was divided into gerahs, 20 to a shekel (Ex 30:13). The gerah (gerah) is supposed to be some kind of seed, perhaps a bean or some such plant. The shekel of which it formed a part was probably the royal or commercial shekel of 160 grains, derived from Babylon. But the Hebrews certainly had another shekel, called the Phoenician from its being the standard of the Phoenician traders. This would be natural on account of the close connection of the two peoples ever since the days of David and Solomon, but we have certain evidence of it from the extant examples of the monetary shekels of the Jews, which are of this standard, or very nearly so, allowing some loss from abrasion. The Phoenician shekel was about 224 grains, varying somewhat in different localities, and the Jewish shekels now in existence vary from 212 to 220 grains. They were coined after the captivity (see COINS), but whether this standard was in use before we have no means of knowing.
Examples of ancient weights have been discovered in Palestine by archaeological research during recent years, among them one from Samaria, obtained by Dr. Chaplin, bearing the inscription, in Hebrew rebha` netseph. This is interpreted, by the help of the cognate Arabic, as meaning "quarter-half," i.e. of a shekel. The actual weight is 39.2 grains, which, allowing a slight loss, would correspond quite closely to a quarter-shekel of the light Babylonian standard of 160 grains, or the quarter of the half of the double standard. Another specimen discovered at Tell Zakariyeh weighs 154 grains, which would seem to belong to the same standard. The weights, of which illustrations are given in the table, are all in the collection of the Syrian Protestant College, at Beirut, and were obtained from Palestine and Phoenicia and are of the Phoenician standard, which was the common commercial standard of Palestine. The largest, of the spindle or barrel type, weighs 1,350 grains, or 87.46 grams, evidently intended for a 6-shekel weight, and the smaller ones of the same type are fractions of the Phoenician shekel. They were of the same standard, one a shekel and the other a two-shekel weight. They each have 12 faces, and the smaller has a lion stamped on each face save one, reminding us of the lion-weights discovered in Assyria and Babylonia. The spindle weights are of black stone, the others of bronze.
The above is the Phoenician standard. In the Babylonian the shekel would be 160 or 320 grains; the maneh 8,000 or 16,000, and the talent 480,000 or 960,000 grains, according as it was of the light or heavy standard.
