Solomon
Proverbs 11:27ESV·traditional attribution

Whoever diligently seeks good seeks favor, but evil comes to him who searches for it.

Matthew Henry Presbyterian @wholebiblehenry

Observe, 1. Those that are industrious to do good in the world get themselves beloved both with God and man: He that rises early to that which is good (so the word is), that seeks opportunities of serving his friends and relieving the poor, and lays out himself therein, procures favour.

John Gill Reformed Baptist @doctorgill

He that diligently seeketh good,.... Or "early"; who rises early in the morning, as the word (e) signifies, and seeks both to do good, and to enjoy it all the day; who, in the first place, seeks the kingdom of God and his righteousness; who, in the morning of his youth, inquires after the best things; and diligently pursues what is for his own good...

Jamieson-Fausset-Brown Reformed @jfbcommentary

good [and] mischief--that is, of others. procureth . . . seeketh--implying success.
