“And when evening was come, the lord of the vineyard says to his steward, ‘Call the labourers, and pay them their hire, beginning from the last to the first.' ”
Then when evening comes the Estate Owner calls to His manager and tells him to line up the labourers so that they can receive their pay. Paying at the end of the day, on the same day, was a requirement of the Law (Leviticus 19:13). And He tells him to pay the last who were employed first. His gracious treatment continues to the end.
