John Gill Commentary Matthew 26:44

"And he left them again, and went away, and prayed a third time, saying again the same words." — Matthew 26:44 (ASV)

And he left them, and went away again
At some little distance from them; they being so overpowered with sleep, that he could have no conversation with them:

and prayed the third time ;
as the Apostle Paul did, when under temptation, he prayed thrice that it might depart from him, (2 Corinthians 12:8) ,

saying the same words :
the Arabic version renders it, "in the words which he before expressed"; and Munster's Hebrew Gospel reads, "he said the same prayer"; not in the selfsame words, or in the express form he had before delivered it; for it is certain, that his second prayer is not expressed in the same form of words as the first: but the sense is, that he prayed to the same purpose; the matter and substance of his prayer was the same, namely, that he might be exempted from suffering; but if that could not be admitted of, he was desirous to be resigned to the will of his heavenly Father, and was determined to submit unto it.
