SAYEST

sa'-est: "Thou sayest" (Matthew 27:11; Mark 15:2; Luke 22:70, "Ye say"; John 18:37), i.e. rightly; "Thou hast said" (Matthew 26:25,64), = "Yes"; a rabbinical idiom never found in the Old Testament. Mark (Matthew 14:36) renders by "I am." All these passages WHm punctuate interrogatively (compare Kethubhoth, f. 103 b).
