Solomon
Proverbs 10:5ESV·traditional attribution

He who gathers in summer is a prudent son, but he who sleeps in harvest is a son who brings shame.

Matthew Henry Presbyterian @wholebiblehenry

Here is, 1. The just praise of those who improve their opportunities, who take pains to gather and increase what they have, both for soul and body, who provide for hereafter while provision is to be made, who gather in summer, which is gathering time.

John Gill Reformed Baptist @doctorgill

He that gathereth in summer is a wise son,.... Which is the time of gathering the fruits of the earth, and laying them up against winter, as the ant is said to do, Pro 6:8; but he that sleepeth in harvest is a son that causeth shame; to himself, and to his parents and relations.

Jamieson-Fausset-Brown Reformed @jfbcommentary

son--as Pro 1:8, Pro 1:10, and often. sleepeth--in indolence, and not for rest. causeth shame--literally, "is base" (compare Pro 14:35; Pro 17:2).
