Solomon
Proverbs 11:18ESV·traditional attribution

The wicked earns deceptive wages, but one who sows righteousness gets a sure reward.

Matthew Henry Presbyterian @wholebiblehenry

Note, 1. Sinners put a most fatal cheat upon themselves: The wicked works a deceitful work, builds himself a house upon the sand, which will deceive him when the storm comes, promises himself that by his sin which he will never gain; nay, it is cutting his throat when it smiles upon him. Sin deceived me, and by it slew me. 2.

John Gill Reformed Baptist @doctorgill

The wicked worketh a deceitful work,.... Such a wicked man as before described; that neither enjoys the good things of life he has, nor suffers others to enjoy them; and all to accumulate riches, which are deceitful and perishing; and who abstains from meats, which God has created for use, under a pretence of religion, and so deceives his own soul; and indeed every sin...

Jamieson-Fausset-Brown Reformed @jfbcommentary

a deceitful work--or, "wages," which fail to satisfy, or flee away (Pro 10:2; Pro 23:5). sure reward--or, "gain," as from trading (Hos 10:12; Gal 6:8-9).
