Psalm 51/Notes/Lexical.v. 15.709127

יָשׁוּבוּ may be taken to imply that the sinners will "return" to a previously experienced state of proximity to YHWH, but it need not do so. The preferred gloss "turn back" allows for this possibility without requiring it, since the idea of reversal of course (i.e., away from a sinful, contrary trajectory) sufficiently accounts for the semantics of שׁוב.
