18 The verb נוּף (nuf, “cause rain to fall”) is a homonym of the more common נוּף (“brandish”).
19 Heb “[on] your inheritance.” This refers to Israel as God’s specially chosen people (see Pss 28:9; 33:12; 74:2; 78:62, 71; 79:1; 94:5, 14; 106:40). Some take “your inheritance” with what follows, but the vav (ו) prefixed to the following word (note וְנִלְאָה, vénil’ah) makes this syntactically unlikely.
20 Heb “it [is],” referring to God’s “inheritance.”
21 Heb “it,” referring to God’s “inheritance.”
22 The meaning of the Hebrew text is unclear; it appears to read, “your animals, they live in it,” but this makes little, if any, sense in this context. Some suggest that חָיָּה (khayah) is a rare homonym here, meaning “community” ( 312 ) or “dwelling place” ( III *הַיָּה). In this case one may take “your community/dwelling place” as appositional to the third feminine singular pronominal suffix at the end of v. 9, the antecedent of which is “your inheritance.” The phrase יָשְׁבוּ־בָהּ (yashvu-vah, “they live in it”) may then be understood as an asyndetic relative clause modifying “your community/dwelling place.” A literal translation of vv. 9b–10a would be, “when it [your inheritance] is tired, you sustain it, your community/dwelling place in [which] they live.”
