Bible. N.T. John 1.35-38, "Again the next day after, John stood, and two of his disciples; And looking upon Jesus as he walked, he saith, Behold the Lamb of God! And the two disciples heard him speak, and they followed Jesus.". The two disciples pictured are mentioned in John 1.37-38 as John the Baptist's followers, who desert him on seeing Christ. One is identified as Andrew, Peter's brother (1.40). Here, one of them reads a scroll of Hebrew scripture for predictions of Christ's arrival, and the other, disrobed for baptism in the nearby pool, rests his head in his hands. On the ground are a hat and crook. Behind Jesus a flock of sheep rests in front of a city. But next to them, on the left, is a tree felled by an axe (Matthew 3.7-10; Luke 3.7-9)
