Sayest
International Standard Bible Encyclopedia · James Orr and contributors
sa'-est: "Thou sayest" (Mt 27:11; Mr 15:2; Lu 22:70, "Ye say"; Joh 18:37), i.e. rightly; "Thou hast said" (Mt 26:25,64), = "Yes"; a rabbinical idiom never found in the Old Testament. Mr 14:62 renders by "I am." All these passages WHm punctuate interrogatively (compare Kethubhoth, f. 103 b).
