He that gathereth in summer is a wise son: but he that sleepeth in harvest is a son that causeth shame.
– Proverbs 10:5
[T]his proverb contrasts hard work and slothfulness, which is a common theme throughout the Proverbs. Rather than focusing on diligence and abundance contrasted with slothfulness and poverty, this proverb focuses on the effects a son has on his parents. A wise son brings joy (Proverbs 15:20) and a foolish son brings grief (Proverbs 17:25). Looking a little deeper at the proverb, we see the core of it is not so much about industry versus laziness as it is wisdom. The summer and the harvest are seasons that require certain things to be done. The wise son gathers because he discerns the season and is diligent at the appropriate time. The shameful son either doesn’t discern the time or carelessly sleeps, both bringing shame.
