Charles Ellicott Commentary Psalms 57:3

"He will send from heaven, and save me, [When] he that would swallow me up reproacheth; Selah God will send forth his lovingkindness and his truth." — Psalms 57:3 (ASV)

He shall send ... —The selah in the middle of this verse is as much out of place as in Psalm 55:19. The Septuagint places it after Psalm 57:2. The marginal correction of the second clause is decidedly to be adopted; the word “reproach” is used here in the sense of “rebuke.” For the verb “send,” used absolutely, compare to Psalm 18:16.
