For my own sake, even for my own sake, will I do it: for how should my name {n} be profaned? {o} and I will not give my glory to another.

(n) God joins the salvation of his with his own honour: so that they cannot perish, but his glory would be diminished, as in De 32:27.

(o) Read Isa 42:8.

Wesley's Notes

48:11 It - This great work of delivering my people out of Babylon. Name - If I should not deliver my people, my name would be profaned and blasphemed. Glory - I will not give any colour to idolaters, to ascribe the divine nature and properties, to idols, as they would do if I did not rescue my people out of their hands in spite of their idols.

Jamieson-Fausset-Brown Bible Commentary

11. how should my name-Maurer, instead of "My name" from Isa 48:9, supplies "My glory" from the next clause; and translates, "How (shamefully) My glory has been profaned!" In English Version the sense is, "I will refrain (Isa 48:9, that is, not utterly destroy thee), for why should I permit My name to be polluted, which it would be, if the Lord utterly destroyed His elect people" (Eze 20:9)?

not give my glory unto another-If God forsook His people for ever, the heathen would attribute their triumph over Israel to their idols; so God's glory would be given to another.

Matthew Henry's Concise Commentary

48:9-15 We have nothing ourselves to plead with God, why he should have mercy upon us. It is for his praise, to the honour of his mercy, to spare. His bringing men into trouble was to do them good. It was to refine them, but not as silver; not so thoroughly as men refine silver. If God should take that course, they are all dross, and, as such, might justly be put away. He takes them as refined in part only. Many have been brought home to God as chosen vessels, and a good work of grace begun in them, in the furnace of affliction. It is comfort to God's people, that God will secure his own honour, therefore work deliverance for them. And if God delivers his people, he cannot be at a loss for instruments to be employed. God has formed a plan, in which, for his own sake, and the glory of his grace, he saves all that come to Him.
