Matthew
Matthew 26:42BSB·traditional attribution

A second time He went away and prayed, “My Father, if this cup cannot pass unless I drink it, may Your will be done.”

John Calvin Reformed @genevareformer

42. Again he went away a second time. By these words Christ seems as if, having subdued fear, he came with greater freedom and courage to submit to the will of the Father; for he no longer asks to have the cup removed from him, but, leaving out this prayer, insists rather on obeying the purpose of God.

And he came and found them asleep again,.... For they were aroused and awaked, in some measure, by what he had said to them; but no sooner was he gone but they fell asleep again, and thus he found them a second time; or, "he came again and found them asleep"; so read the Vulgate Latin, the Syriac, Arabic, and Ethiopic versions, and Munster's Hebrew...

Verses 42-44. It is probable that our Lord spent considerable time in prayer, and that the evangelists have recorded rather the substance of his petitions than the very words. He returned repeatedly to his disciples, doubtless to caution them against danger; to show the deep interest which he had in their welfare; and to show them the extent of his sufferings on their behalf.
