Isaiah 40:16

40:16 Not even Lebanon could supply enough firewood for a sacrifice; ¹ 

its wild animals would not provide enough burnt offerings. ² 

Isaiah 48:10

48:10 Look, I have refined you, but not as silver;

I have purified you ³  in the furnace of misery.

[40:16]  ¹ tn The words “for a sacrifice” are supplied in the translation for clarification.

[40:16]  ² sn The point is that not even the Lebanon forest could supply enough wood and animals for an adequate sacrifice to the Lord.

[48:10]  ³ tc The Hebrew text has בְּחַרְתִּיךָ (bÿkhartikha, “I have chosen you”), but the Qumran scroll 1QIsa^a reads correctly בחנתיכה (“I have tested you”). The metallurgical background of the imagery suggests that purification through testing is the idea.
