And he said, The kingdom of heaven is of that kind, as if a man should cast seed into his field;

But when Jesus saw it, he felt indignation, and said to them, Permit little children to come to me, and hinder them not; for of such is the kingdom of heaven.

"My sons, how hard it is for those who trust in money to enter the kingdom of God. It is easier for a camel to get through the eye of a needle, than for a rich man to enter the kingdom of heaven."
