Charles H. Spurgeon on Psalms 69:28

Let them be blotted out of the book of the living. Though in their conceit they wrote themselves among the people of God, and induced others to regard them under that character, they shall be unmasked and their names removed from the register. Enrolled with honour, they shall be erased with shame. Death shall obliterate all recollection of them; they shall be held no longer in esteem, even by those who paid them homage. Judas first, and Pilate, and Herod, and Caiaphas, all in due time, were speedily wiped out of existence; their names only remain as bywords, but among the honoured men who live after their departure they are not recorded. And not be written with the righteous. This clause is parallel with the former, and shows that the inner meaning of being blotted out from the book of life is to have it made evident that the name was never written there at all. Man in his imperfect copy of God's book of life will have to make many emendations, both of insertion and erasure; but, as before the Lord, the record is for ever fixed and unalterable. Beware, O man, of despising Christ and his people, lest thy soul should never partake in the righteousness of God, without which men are condemned already. Imprecations, prophecies, and complaints are ended, and prayer of a milder sort begins, intermingled with bursts of thankful song, and encouraging foresight of coming good.
