Yesaya 1:25

1:25 I will attack you; ¹ 

I will purify your metal with flux. ² 

I will remove all your slag. ³ 

Yesaya 63:10

63:10 But they rebelled and offended ⁴  his holy Spirit, ⁵ 

so he turned into an enemy

and fought against them.

[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.

[63:10]  ⁴ tn Or “grieved, hurt the feelings of.”

[63:10]  ⁵ sn The phrase “holy Spirit” occurs in the OT only here (in v. 11 as well) and in Ps 51:11 (51:13 HT), where it is associated with the divine presence.
