saying, ‘These last worked only one hour, and you have made them equal to us who have borne the burden of the day and the scorching heat.’

John Gill Reformed Baptist @doctorgill

But he answered one of them,.... Who was the forwardest and loudest in his complaints, and represented the rest; and said, friend, I do thee no wrong; by giving all alike, the same privileges and blessings to the last, as to the first, since nothing was withheld from him.

Albert Barnes Presbyterian @notesbybarnes

Verse 12. The burden and the heat of the day. The burden means the heavy labour, the severe toil. We have continued at that toil, in the heat of the day. The others had worked only a little while, and that in the cool of the evening, and when it was far more pleasant and much less fatiguing. (1) "have wrought", or, "have continued one hour only"

Jamieson-Fausset-Brown Reformed @jfbcommentary

Saying, These last have wrought but one hour, and thou hast made them equal unto us, which have borne the burden and heat--the burning heat. of the day--who have wrought not only longer but during a more trying period of the day.
