The Lamb of God

grows out of · behold the Lamb

John the Baptist's title for Jesus draws on the Passover lamb and the daily temple offerings at once, and John's Gospel keeps the Passover clock running to the crucifixion.

grows out of · led like a lamb

Isaiah's image of a lamb led to slaughter stands behind John's title as much as the Passover does.

grows out of · the same title

John's Gospel opens with the title and John's Revelation closes with it, now as the name of the one worthy to open the scroll.
