Psalm 133/Notes/Grammar.v. 1.185334

v. 1c – The function of גַּם is not immediately 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" (2009, 329) and "impossible to explain in terms of [his] current model" (2009, 329, n. 44). Nevertheless, גַּם is often employed as a focus particle, preceding an individual sentence constituent, as here. The two common functions of גַּם as a focus particle are additive (≈ "also") and scalar (≈ "even"). The latter seems most probable in the present case, and implies that brothers (probably referring to Israel and Judah as a whole; see story behind) dwelling in the land is a good thing in itself—not only dwelling in the land YHWH had promised them, but even together, under a united monarchy, manifested in the entire nation assembling in Jerusalem to worship.
