[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.
[48:10] 4 tc The Hebrew text has בְּחַרְתִּיךָ (bÿkhartikha, “I have chosen you”), but the Qumran scroll 1QIsaa reads correctly בחנתיכה (“I have tested you”). The metallurgical background of the imagery suggests that purification through testing is the idea.
