But thou hast saved us from our enemies - That is, Thou hast done it in times past. Thou hast interposed in behalf of our nation in periods of danger and trial, and hast delivered us. This is stated as a reason for what is said by the psalmist in Psalm 44:6 - that he would not trust in his sword and in iris bow - and for the earnest appeal which he now makes to God. He and his people did not rely on their own strength and prowess, but on that God who had often interposed to save the nation.
And hast put them to shame that hated us - In former times. That is, he had caused them to be discomfited. He had turned them back. He had covered them with confusion. On the meaning of the words "shame" and "ashamed," see Job 6:20, note; Psalm 34:5, note.

But thou hast saved us from our enemies,.... Spiritual ones, and not we ourselves; and therefore will not trust in ourselves, nor in anything of ours, but in the Lord, and give him the glory of salvation;
and hast put them to shame that hated us; the men of the world, the seed of the serpent, and the serpent himself, when his works were destroyed, and his principalities and powers spoiled by Christ upon the cross; hence the following boasting of the Lord, and glorying in him.

put . . . to shame--(compare Psalm 6:10), disgraced.
