Albert Barnes Commentary Psalms 70:3

"Let them be turned back by reason of their shame That say, Aha, aha." — Psalms 70:3 (ASV)

Let them be turned back for a reward of their shame - The only change which occurs in this verse is the substitution of the milder phrase “Let them be turned back,” for “Let them be desolate.” See the notes at (Psalms 40:15).
