Bereshis 22:6-8

Orthodox Jewish Bible

⁶ And Avraham took atzei haolah (the wood of the burnt offering), and laid it upon Yitzchak his son; and he took the eish (fire) in his hand, and a knife; and they went both of them together.

⁷ And Yitzchak spoke unto Avraham his father, and said, Avi (My father): and he said, Hineini, beni (Here am I, my son). And he said, Hinei, the eish (fire) and the wood: but where is the seh (lamb) for a burnt offering? [YESHAYAH 53:7]

⁸ And Avraham said, My son, G-d will provide Himself a seh (lamb) for a burnt offering: so they went both of them together.
