Charles Ellicott Commentary Proverbs 30:9

"Lest I be full, and deny [thee], and say, Who is Jehovah? Or lest I be poor, and steal, And use profanely the name of my God." — Proverbs 30:9 (ASV)

Lest I be full, and deny thee.— For pride and fulness of bread were among the sins which brought destruction on Sodom (Ezekiel 16:49). (Compare to Job 21:14-15.)

And take the name of my God in vain.— Literally, handle it roughly, irreverently; particularly in finding fault with His providence.
