Matthew 20:2-6

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.

And about the eleventh hour he went out, and found others standing idle, and saith unto them, Why stand ye here all the day idle?
