Mark 10:13-15

13Then they brought little children to Him, that He might touch them; but the disciples rebuked those who brought them.

14But when Jesus saw it, He was greatly displeased and said to them, “Let the little children come to Me, and do not forbid them; for of such is the kingdom of God.

15Assuredly, I say to you, whoever does not receive the kingdom of God as a little child will by no means enter it.”
