Yesaya 28:9

28:9 Who is the Lord ¹  trying to teach?

To whom is he explaining a message? ² 

Those just weaned from milk!

Those just taken from their mother’s breast! ³ 

Yesaya 11:9

11:9 They will no longer injure or destroy

on my entire royal mountain. ⁴ 

For there will be universal submission to the Lord’s sovereignty,

just as the waters completely cover the sea. ⁵ 

[28:9]  ¹ tn Heb “he”; the referent (the Lord) has been specified in the translation for clarity.

[28:9]  ² tn Heb “Who is he teaching knowledge? For whom is he explaining a message?” The translation assumes that the Lord is the subject of the verbs “teaching” and “explaining,” and that the prophet is asking the questions. See v. 12. According to some vv. 9-10 record the people’s sarcastic response to the Lord’s message through Isaiah.

[28:9]  ³ tn Heb “from the breasts.” The words “their mother’s” are supplied in the translation for clarification. The translation assumes that this is the prophet’s answer to the questions asked in the first half of the verse. The Lord is trying to instruct people who are “infants” morally and ethically.

[11:9]  ⁴ tn Heb “in all my holy mountain.” In the most basic sense the Lord’s “holy mountain” is the mountain from which he rules over his kingdom (see Ezek 28:14, 16). More specifically it probably refers to Mount Zion/Jerusalem or to the entire land of Israel (see Pss 2:6; 15:1; 43:3; Isa 56:7; 57:13; Ezek 20:40; Ob 16; Zeph 3:11). If the Lord’s universal kingdom is in view in this context (see the note on “earth” at v. 4), then the phrase would probably be metonymic here, standing for God’s worldwide dominion (see the next line).

[11:9]  ⁵ tn Heb “for the earth will be full of knowledge of the Lord, as the waters cover the sea.” The translation assumes that a universal kingdom is depicted here, but אֶרֶץ (’erets) could be translated “land” (see the note at v. 4). “Knowledge of the Lord” refers here to a recognition of the Lord’s sovereignty which results in a willingness to submit to his authority. See the note at v. 2.
