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.
