John Lightfoot on Matthew 20:1

[Who went out early in the morning to hire labourers.] You have such a parable as this, but madly applied, in the Talmud: we will produce it here for the sake of some phrases: "To what was R. Bon Bar Chaija like? To a king who hired many labourers; among which there was one hired, who performed his work extraordinary well. What did the king? He took him aside, and walked with him to and fro. When even was come, those labourers came, that they might receive their hire, and he gave him a complete hire with the rest. And the labourers murmured, saying, 'We have laboured hard all the day, and this man only two hours, yet he hath received as much wages as we': the king saith to them, 'He hath laboured more in those two hours than you in the whole day.' So R. Bon plied the law more in eight-and-twenty years than another in a hundred years."

[Early in the morning.] "The time of working is from sunrising to the appearing of the stars, and not from break of day: and this is proved from the chapter the president of the priests saith to them; where they say, 'It is light all in the east, and men go out to hire labourers': whence it is argued that they do not begin their work before the sun riseth. It is also proved from the tract Pesachin, where it is said that it is prohibited on the day of the Passover to do any servile work after the sun is up; intimating this, that that was the time when labourers should begin their work," &c.

[To hire labourers.] Read here, if you please, the tract Bava Mazia, cap. 7; which begins thus, He that hireth labourers: and Maimonides, a tract entitled Hiring.
