sin'-u (gidh (Job 10:11, etc.)): The tendons and sinews of the body are uniformly (7 times) thus called. "Therefore the children of Israel eat not the sinew of the hip which is upon the hollow of the thigh, unto this day: because he touched the hollow of Jacob's thigh in the sinew of the hip" (Ge 32:32). In the poetical description of Behemoth (hippopotamus) it is said: "He moveth his tail like a cedar: the sinews of his thighs are knit together" (Job 40:17). The prophet Ezekiel saw in his vision (Job 37:6,8) that the dry bones were gathered together, that they were covered with sinews, flesh and skin, and that they were revived by the spirit of the Lord. In figurative language the neck of the obstinate is compared to an "iron sinew" (Isa 48:4). the King James Version "my sinews take no rest" (we`oreqay lo' yishkabhun, Job 30:17) has been corrected by the Revised Version (British and American) into "the pains that gnaw me take no rest," but the earlier version has been retained in the margin.
