Charles Ellicott 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)

There are two unimportant variations from Psalm 14:0 here: “every one,” instead of “the whole,” and “gone back” (sag) for “gone aside” (sar).
