Psalms 57:3

Reproach - Disgrace; shame.

Save - Except; besides.

He shall send from heaven, and save me - Were there no human agents or earthly means that he could employ, he would send his angels from heaven to rescue me from my enemies. Or, He will give his command from heaven that this may be done on earth.

Selah - I think this word should be at the end of the verse.

God shall send forth his mercy and his truth - Here mercy and truth are personified. They are the messengers that God will send from heaven to save me. His mercy ever inclines him to help and save the distressed. This he has promised to do; and his truth binds him to fulfll the promises or engagements his mercy has made, both to saints and sinners.

He shall send from heaven - That is, from himself; or, he will interpose to save me. The psalmist does not say "how" he expected this interposition - whether by an angel, by a miracle, by tempest or storm, but he felt that help was to come from God alone, and he was sure that it would come.

And save me from the reproach ... - This would be more correctly rendered, "He shall save me; he shall reproach him that would swallow me up." So it is rendered in the margin. On the word rendered "would swallow me up," see the notes at Psalm 56:1. The idea here is, that God would "rebuke" or "reproach," to wit, by overthrowing him that sought to devour or destroy him. God had interposed formerly in his behalf Psalm 57:2, and he felt assured that he would do it again.

Selah - This seems here to be a mere musical pause. It has no connection with the sense. See the notes at Psalm 3:2.

God shall send forth his mercy - In saving me. He will "manifest" his mercy.

And his truth - His fidelity to his promise; his faithfulness to those who put their trust in him. He will show himself "true" to all the promises which he has made. Compare Psalm 40:11.

57:3 Send forth - Will discover them, by affording his gracious help in pursuance of his promises.
