Solomon
Proverbs 12:10ESV·traditional attribution

Whoever is righteous has regard for the life of his beast, but the mercy of the wicked is cruel.

Matthew Henry Presbyterian @wholebiblehenry

See here, 1. To how great a degree a good man will be merciful; he has not only a compassion for the human nature under its greatest abasements, but he regards even the life of his beast, not only because it is his servant, but because it is God's creature, and in conformity to Providence, which preserves man and beast.

John Gill Reformed Baptist @doctorgill

A righteous man regardeth the life of his beast,.... Or "knoweth" it (q); knows the worth of it and values it, and takes care of it, and is concerned for the preservation of it; he provides sufficient food for it, and gives it; he does not overwork it, but allows it proper rest from labour; and, if in any disorder, will make use of all...

Jamieson-Fausset-Brown Reformed @jfbcommentary

regardeth--literally, "knoweth" (Psa 1:6). mercies . . . cruel--as acts of compassion ungraciously rendered to the needy. The righteous more regards a beast than the wicked a man.
