Charles Ellicott Commentary Proverbs 19:21

"There are many devices in a man`s heart; But the counsel of Jehovah, that shall stand." — Proverbs 19:21 (ASV)

There are many devices (or, thoughts) in a man’s heart. —He disquiets himself in vain (Psalms 39:6), endeavoring to carry out his various plans in life, while the one unchangeable “counsel of the Lord,” that shall stand—that is, abide in all its fullness. (Psalms 33:11; Job 23:13.)
