Charles Ellicott Commentary Isaiah 48:11

"For mine own sake, for mine own sake, will I do it; for how should [my name] be profaned? and my glory will I not give to another." — Isaiah 48:11 (ASV)

Will I do it ... —The neuter pronoun includes the whole work of redemption.

For how should my name be polluted? —The italics show that "my name" is not in the Hebrew, but the context requires its insertion as from Isaiah 48:9, or that of "my glory" from the clause that follows. The "pollution" or desecration of the name of Jehovah would follow, it is implied, on the non-completion of His redeeming work.
