Psalm 133/Notes/Grammar.v. 1.185334
From Psalms: Layer by Layer
v. 1c – The function of גַּם is not altogether clear. None of the ancient versions (or modern versions consulted) contain a direct gloss of the lexeme, while van der Merwe's study of גַּם considers it "problematic"[1] and "impossible to explain in terms of [his] current model."[2] Nevertheless, גַּם is often employed as a focus particle, preceding an individual sentence constituent, as here, so may communicate a scalar sense of "even."
