Isaac calls his father and Abraham answers: "Hineni" ("Here am I", Genesis 22:6), a quotation from Isaiah 6:8 (the calling of the prophet Isaiah): "And I heard the voice of the Lord, saying 'Whom shall I send, and who will go for us?' Then I said, 'Here am I! Send me.' " On New Year's Day (Rosh Hashanah), believers repeat this answer.
