Matthew 18:1
1 At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?"
2 And calling to him a child, he put him in the midst of them
3 and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.
4 Whoever humbles himself like this child is the greatest in the kingdom of heaven.
Joseph and Jesus, Guido Reni, 1635
