[1:25]  ¹ tn Heb “turn my hand against you.” The second person pronouns in vv. 25-26 are feminine singular. Personified Jerusalem is addressed. The idiom “turn the hand against” has the nuance of “strike with the hand, attack,” in Ps 81:15 HT (81:14 ET); Ezek 38:12; Am 1:8; Zech 13:7. In Jer 6:9 it is used of gleaning grapes.

[1:25]  ² tn Heb “I will purify your dross as [with] flux.” “Flux” refers here to minerals added to the metals in a furnace to prevent oxides from forming. For this interpretation of II בֹּר (bor), see HALOT 153 s.v. II בֹּר and 750 s.v. סִיג.

[1:25]  ³ sn The metaphor comes from metallurgy; slag is the substance left over after the metallic ore has been refined.

[45:17]  ⁴ tn Heb “Israel will be delivered by the Lord [with] a permanent deliverance.”

[45:17]  ⁵ tn Heb “you will not be ashamed and you will not be humiliated for ages of future time.”

[54:7]  ⁷ tn Or “forsook” (NASB).
