10 The verb תָשׁוּב (tashuv, Qal imperfect 2nd person masculine singular from שׁוּב, shuv, “to return”) functions as an imperfect of moral obligation, introducing the following imperatives (e.g., Gen 20:9; Exod 4:15). For this function of the imperfect, see §31.4g.
11 The verb וְקַוֵּה (véqavveh, vav + Piel imperative 2nd person masculine singular from קָוָה, qavah, “to wait for”) means “to hope for, wait for, look eagerly for” ( 875 קָוָה 1; קָוָה 2.b). The Qal meaning refers to a general hope; the Piel meaning refers to hope directed toward an object, or hope inserted within a sequence of expectation and fulfillment. When the Piel is used in reference to a thing, it refers to waiting expectantly for something to occur (e.g., Gen 49:18; Isa 5:2, 4, 7; 59:9, 11; Jer 8:15; 13:16; 14:19; Ps 69:21; Job 3:9; 6:19; 11:20). When it is used in reference to God, it refers to the people of God waiting expectantly for God to do something or to fulfill his promise (e.g., Pss 25:5, 21; 27:14; 37:34; 40:2; 52:11; 130:5; Isa 8:17; 25:9; 26:8; 33:2; 51:5; 60:9; Hos 12:7). The personal object can be introduced by the preposition לְ (lamed, “for”; קָוָה 2.a) or אֶל (’el, “for”; קָוָה 2.b; e.g., Pss 27:14; 37:34; Isa 51:5; Hos 12:7). The point seems to be that if Israel will repent and practice moral righteousness, she can look to God in confident expectation that he will intervene on her behalf by relenting from judgment and restoring the covenant blessings.
12 The phrase “to return to you” does not appear in the Hebrew text but is implied; it is provided in the translation for clarity. This ellipsis fills out the implicit connotations of the verb קָוָה (qavah, “to wait for”).
