Matthew 20:3-7

The third hour would be about 9:00 a.m., the sixth hour about noon, and the eleventh hour about 5:00 p.m. The market place would have been the central square of the town where day laborers obtained work and pay. The landowner did not promise a particular wage, only that He would deal justly with the laborers. Jesus did not explain why the landowner kept hiring more workers throughout the day. That was an irrelevant detail in His story. All the workers trusted the landowner to give them what was fair at the end of the day.

"The day laborer did not have even the minimal security which a slave had in belonging to one master. There was no social welfare program on which an unemployed man could fall back, and no trade unions to protect a worker’s rights. An employer could literally ’do what he chose with what belonged to him’ (Matthew 20:15)." [Note: France., The Gospel . . ., p. 749.]
