Matthew Henry Commentary Proverbs 24:21-22

"My son, fear thou Jehovah and the king; [And] company not with them that are given to change: For their calamity shall rise suddenly; And the destruction from them both, who knoweth it?" — Proverbs 24:21-22 (ASV)

The godly in the land will be quiet in the land. There may be cause to change for the better, but have nothing to do with those who are given to change.
