Fool. — Heb., nabal, from a root meaning “to wither;” hence flat, insipid (insipiens). But this is not therefore speculative atheism, but practical — a denial of the moral government of God — so that fool and wicked become almost synonymous.
They have done abominable works. — Literally, they have made to be abhorred their works. The LXX. and Vulg. have caught the sense, “They have become abominable in their practices.” Instead of works, Psalms 53 has “iniquity.”
