Psalm 37/Notes/Textual.vv. 39-40.824422
From Psalms: Layer by Layer
v. 39: Some textual witnesses omit the waw in וּתְשׁוּעַת in order to "fix" the acrostic structure (see e.g., Jerome iuxta Hebr., two mss in Kennicott). The oldest witnesses, however, have the waw (e.g., 4Q171 ות[שועת...]; LXX: σωτηρία δὲ).
