1 tn Heb “[one of] firm purpose you will keep [in] peace, peace, for in you he possesses trust.” The Hebrew term יֵצֶר (yetser) refers to what one devises in the mind; סָמוּךְ (samukh) probably functions here like an attributive adjective and carries the nuance “firm.” So the phrase literally means, “a firm purpose,” but as the object of the verb “keep, guard,” it must stand by metonymy for the one(s) who possess a firm purpose. In this context the “righteous nation” (v. 2) is probably in view and the “firm purpose” refers to their unwavering faith in God’s vindication (see 25:9). In this context שָׁלוֹם (shalom, “peace”), which is repeated for emphasis, likely refers to national security, not emotional or psychological composure (see vv. 1-2). The passive participle בָּטוּחַ (batuakh) expresses a state that results from the subject’s action.
2 tn Heb “O Lord, you establish peace for us.”
3 tc Some suggest emending גַּם כָּל (gam kol, “even all”) to כִּגְמֻל (kigmul, “according to the deed[s] of”) One might then translate “for according to what our deeds deserve, you have acted on our behalf.” Nevertheless, accepting the MT as it stands, the prophet affirms that Yahweh deserved all the credit for anything Israel had accomplished.
