Isaiah 26:3

26:3 You keep completely safe the people who maintain their faith,

for they trust in you. ¹ 

Isaiah 28:10

28:10 Indeed, they will hear meaningless gibberish,

senseless babbling,

a syllable here, a syllable there. ² 

Isaiah 57:7

57:7 On every high, elevated hill you prepare your bed;

you go up there to offer sacrifices.

[26:3]  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.

[28:10]  ² tn The meaning of this verse has been debated. The text has literally “indeed [or “for”] a little there, a little there” ( כִּי צַו לָצָו צַו לָצָו קַו לָקָו קַו, ki tsav latsav, tsav latsav, qav laqav, qav laqav). The present translation assumes that the repetitive syllables are gibberish that resembles baby talk (cf v. 9b) and mimics what the people will hear when foreign invaders conquer the land (v. 11). In this case זְעֵיר (zÿ’er, “a little”) refers to the short syllabic structure of the babbling (cf. CEV). Some take צַו (tsav) as a derivative of צָוָה (tsavah, “command”) and translate the first part of the statement as “command after command, command after command.” Proponents of this position (followed by many English versions) also take קַו (qav) as a noun meaning “measuring line” (see v. 17), understood here in the abstract sense of “standard” or “rule.”
