Matthew 20:11

For the kingdom of heaven is like unto a man that is an householder, which went out early in the morning to hire labourers into his vineyard.

And when he had agreed with the labourers for a penny a day, he sent them into his vineyard.

And he went out about the third hour, and saw others standing idle in the marketplace,

And said unto them; Go ye also into the vineyard, and whatsoever is right I will give you. And they went their way.

Again he went out about the sixth and ninth hour, and did likewise.
