[10:21] 1 tn The referent of אֵל גִּבּוֹר (’el gibbor, “mighty God”) is uncertain. The title appears only here and in 9:6, where it is one of the royal titles of the coming ideal Davidic king. (Similar titles appear in Deut 10:17 and Neh 9:32 [“the great, mighty, and awesome God”] and in Jer 32:18 [“the great and mighty God”]. Both titles refer to God.) Though Hos 3:5 pictures Israel someday seeking “David their king,” and provides some support for a messianic interpretation of Isa 10:21, the Davidic king is not mentioned in the immediate context of Isa 10:21 (see Isa 11, however). The preceding verse mentions Israel relying on the Lord, so it is likely that the title refers to God here.
[31:6] 2 tn Heb “Return to the one [against] whom the sons of Israel made deep rebellion.” The syntax is awkward here. A preposition is omitted by ellipsis after the verb (see GKC 446 §138.f, n. 2), and there is a shift from direct address (note the second plural imperative “return”) to the third person (note “they made deep”). For other examples of abrupt shifts in person in poetic style, see GKC 462 §144.p.
