Isaiah 7:9

7:9 Ephraim’s leader is Samaria,

and Samaria’s leader is the son of Remaliah.

If your faith does not remain firm,

then you will not remain secure.” 1 

Isaiah 66:22

66:22 “For just as the new heavens and the new earth I am about to make will remain standing before me,” says the Lord, “so your descendants and your name will remain.

1 tn Heb “if you do not believe, you will not endure.” The verb forms are second plural; the Lord here addresses the entire Davidic family and court. (Verse 4 was addressed to the king.) There is a wordplay in the Hebrew text, designed to draw attention to the alternatives set before the king (cf. 1:20). “Believe” (תַאֳמִינוּ, ta’aminu) is a Hiphil form of the verb אָמָן (’aman); “endure” (תֵאָמֵנוּ, te’amenu) is a Niphal form of this same verb.
