People were bringing children to Jesus so that he would bless them. But the disciples scolded them.
References for Mark 10:13
When Jesus saw this, he grew angry and said to them, "Allow the children to come to me. Don't forbid them, because God's kingdom belongs to people like these children.
I assure you that whoever doesn't welcome God's kingdom like a child will never enter it."
Then he hugged the children and blessed them.
