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 The Hebrew text has, “yes, the way of your judgments.” The translation assumes that “way” is related to the verb “we wait” as an adverbial accusative (“in the way of your judgments we wait”). מִשְׁפָּטֶיךָ (mishpatekha, “your judgments”) could refer to the Lord’s commandments, in which case one might translate, “as we obey your commands.” However, in verse 9 the same form refers to divine acts of judgment on evildoers.
