John 1:29

Verse 29. The next day . The day after the Jews made inquiry whether he was the Christ. Behold the Lamb of God. A lamb, among the Jews, was killed and eaten at the Passover to commemorate their deliverance from Egypt, Ex 12:3-11. A lamb was offered in the tabernacle, and afterward in the temple, every morning and evening, as a part of the daily worship, Ex 29:38,39. The Messiah was predicted as a lamb led to the slaughter, to show his patience in his sufferings, and readiness to die for man, Isa 53:7. A lamb, among the Jews, was also an emblem of patience, meekness, gentleness. On all these accounts, rather than on any one of them alone, Jesus was called the Lamb.
