Behold the Lamb

John 1:29 APNT And on the next day, John saw Jesus, who was coming towards him and said, “Behold, the Lamb of God who takes away the sin of the world.  [takes away = bears, take on oneself]

1 Pet. 1:18-21 APNT knowing that you were not redeemed with silver that is corruptible, nor with gold, by your empty works that you received from your fathers,

 19 but with the precious blood of the lamb, who has no spot or blemish, who is Christ.

 20 He was previously appointed to this before the foundations of the world and was revealed in the end of times for you,

 21 who by way of him have believed in God, who raised him from the dead and gave him glory, that your faith and your hope would be in God.

1 Peter 1:3 APNT Blessed be God, the Father of our Lord Jesus Christ, who by his great mercy has fathered us anew to the hope of life by the resurrection of Jesus Christ,

Jesus was the lamb at the feast of Passover and fulfilled all the details that happened during the feast.
