Luke 2:1-7; John 1:29 Behold the Lamb of God

Luke 2:1–7 (ESV)
1In those days a decree went out from Caesar Augustus that all the world should be registered.
2This was the first registration when Quirinius was governor of Syria.
3And all went to be registered, each to his own town.
4And Joseph also went up from Galilee, from the town of Nazareth, to Judea, to the city of David, which is called Bethlehem, because he was of the house and lineage of David,
5to be registered with Mary, his betrothed, who was with child.
6And while they were there, the time came for her to give birth.
7And she gave birth to her firstborn son and wrapped him in swaddling cloths and laid him in a manger, because there was no place for them in the inn.

John 1:29 (ESV)
29The next day he saw Jesus coming toward him, and said, "Behold, the Lamb of God, who takes away the sin of the world!
