John Gill Commentary Psalms 53:3

"Every one of them is gone back; they are together become filthy; There is none that doeth good, no, not one." — Psalms 53:3 (ASV)

Every one of them is gone back From God, and the way of his commandments.

In (Psalms 14:3) , it is, "they are all gone aside"; (See Gill on Psalms 14:3);

they are altogether become filthy; [there is] none that does good , no, not one .

What follows in this verse is the same as (Psalms 14:3) .
