¹ sn The personified heavens and earth are summoned to God’s courtroom as witnesses against God’s covenant people. Long before this Moses warned the people that the heavens and earth would be watching their actions (see Deut 4:26; 30:19; 31:28; 32:1).

² tn Or “sons” (NAB, NASB).

sn “Father” and “son” occur as common terms in ancient Near Eastern treaties and covenants, delineating the suzerain and vassal as participants in the covenant relationship. The prophet uses these terms, the reference to heavens and earth as witnesses, and allusions to deuteronomic covenant curses (1:7-9, 19-20) to set his prophecy firmly against the backdrop of Israel’s covenantal relationship with Yahweh.

³ sn The normal word pair for giving birth to and raising children is יָלַד (yalad, “to give birth to”) and גָּדַל (gadal, “to grow, raise”). The pair גָּדַל and רוּם (rum, “to raise up”) probably occur here to highlight the fact that Yahweh made something important of Israel (cf. R. Mosis, TDOT 2:403).

⁴ sn Against the backdrop of Yahweh’s care for his chosen people, Israel’s rebellion represents abhorrent treachery. The conjunction prefixed to a nonverbal element highlights the sad contrast between Yahweh’s compassionate care for His people and Israel’s thankless rebellion.

⁵ sn To rebel carries the idea of “covenant treachery.” Although an act of פֶּשַׁע (pesha’, “rebellion”) often signifies a breach of the law, the legal offense also represents a violation of an existing covenantal relationship (E. Carpenter and M. Grisanti, NIDOTTE 3:707).

⁶ sn The “name” of the Lord sometimes stands by metonymy for the Lord himself, see Exod 23:21; Lev 24:11; Pss 54:1 (54:3 HT); 124:8. In Isa 30:27 the point is that he reveals that aspect of his character which his name suggests – he comes as Yahweh (“he is present”), the ever present helper of his people who annihilates their enemies and delivers them. The name “Yahweh” originated in a context where God assured a fearful Moses that he would be with him as he confronted Pharaoh and delivered Israel from slavery in Egypt. See Exod 3.

⁷ tn Heb “his anger burns, and heaviness of elevation.” The meaning of the phrase “heaviness of elevation” is unclear, for מַשָּׂאָה (masa’ah, “elevation”) occurs only here. Some understand the term as referring to a cloud (elevated above the earth’s surface), in which case one might translate, “and in heavy clouds” (cf. NAB “with lowering clouds”). Others relate the noun to מָשָׂא (masa’, “burden”) and interpret it as a reference to judgment. In this case one might translate, “and with severe judgment.” The present translation assumes that the noun refers to his glory and that “heaviness” emphasizes its degree.

⁸ tn Heb “his lips are full of anger, and his tongue is like consuming fire.” The Lord’s lips and tongue are used metonymically for his word (or perhaps his battle cry; see v. 31).
