That they may know that this is thy hand - That this has been done by thee; that it has all occurred under thy direction, or has been ordered by thee. The reference seems to be particularly to God's interposition: "Let it be manifest to all that thou hast interposed in my behalf; that thou hast undertaken for me; that thou art my Friend." He desired an interposition from God that he might be vindicated before all his enemies.

That thou, Lord, hast done it - Let it be such an interposition that it will be manifest to all that no other one but God could have done this.

That they may know that this is thy hand - Let thy help be so manifest in my behalf, that they may see it is thy hand, and that thou hast undertaken for me. Or, if the words refer to the passion of our Lord, Let them see that I suffer not on my own account; "for the transgression of my people am I smitten."

That they may know that this is thy hand,.... Which inflicted vengeance, and executed judgments on Judas and the Jews, as before imprecated: so the Targum,

"that they may know that this is thy stroke;''

or which was concerned in all the sorrows and sufferings of the Messiah, which could never have come upon him had it not been the will of God; it was his hand and council that determined it, or men could never have effected it; see Acts 4:28, or which wrought deliverance and salvation as before prayed for; see Psalm 118:21.

That thou, Lord, hast done it: one or other, or all the above things; the finger of God was to be seen in them; particularly in the sufferings of Christ, and in his exaltation; see Acts 2:23.

That they may know that this is thy hand; that thou, LORD, hast done it.

109:21-31 The psalmist takes God's comforts to himself, but in a very humble manner. He was troubled in mind. His body was wasted, and almost worn away. But it is better to have leanness in the body, while the soul prospers and is in health, than to have leanness in the soul, while the body is feasted. He was ridiculed and reproached by his enemies. But if God bless us, we need not care who curses us; for how can they curse whom God has not cursed; nay, whom he has blessed? He pleads God's glory, and the honour of his name. Save me, not according to my merit, for I pretend to none, but according to thy-mercy. He concludes with the joy of faith, in assurance that his present conflicts would end in triumphs. Let all that suffer according to the will of God, commit the keeping of their souls to him. Jesus, unjustly put to death, and now risen again, is an Advocate and Intercessor for his people, ever ready to appear on their behalf against a corrupt world, and the great accuser.
