Psalms 57:3 - Joseph Benson’s Commentary on the Old and New Testaments

He shall send from heaven Either his angels, as Daniel 3:28, or his power and help in some less extraordinary way. As if he had said, There are greater armies in heaven than those that here surround me; and rather than I should perish, he will send them for my deliverance; and save me from the reproach of him, &c. From that shameful destruction which Saul designs to bring upon me. The Hebrew, however, חר Š שׁאפי, cheereeph shoapi, may be properly rendered, as in the margin, he reproacheth, or hath reproached, that is, he will certainly put to shame, or reproach him that would swallow me up, by disappointing his expectation, and delivering me from his rage. God shall send forth his mercy and truth Shall discover them by their proper fruits, namely, by affording his gracious help in pursuance of his promises. “The reader will observe, that mercy and truth are here poetically represented as ministers of God, standing in his presence, ready to execute his pleasure, and employed by him in the salvation of his people.” Dodd.
