Matthew 19:13-14 says:
13Then the people brought their little children to Jesus so that Jesus could put his hands on them* and pray for them. When the followers saw this, they told the people to stop bringing their children to Jesus. 14But Jesus said, "Let the little children come to me. Don't stop them, because the kingdom of heaven belongs to people that are like these children." (Easy-to-Read Version)
King James Version:
13Then were there brought unto him little children, that he should put his hands on them, and pray: and the disciples rebuked them. 14But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.
