21 The Hebrew text has לְסַרְבֵּה (lémarbeh), which is a corrupt reading. לם is dittographic; note the preceding word, שָׁלוֹם (shalom). The corrected text reads literally, “great is the dominion.”
22 Heb “and to peace there will be no end” ( and both similar). On the political and socio-economic sense of שָׁלוֹם (shalom) in this context, see the note at v. on “Prince of Peace.”
23 Heb “over the throne of David, and over his kingdom.” The referent of the pronoun “his” (i.e., David) has been specified in the translation for clarity.
24 The feminine singular pronominal suffix on this form and the following one (translated “it” both times) refers back to the grammatically feminine noun “kingdom.”
25 Heb “with/by justice and fairness”; “with justice and with righteousness.”
26 Heb “the zeal of the Lord.” In this context the Lord’s “zeal” refers to his intense devotion to and love for his people which prompts him to vindicate them and to fulfill his promises to David and the nation.
