Proverbs 21:20

Wise men lay up all necessary and desirable treasures for their own use, and for their children and families. Oil is particularly mentioned, partly because that was a considerable part of their wealth and treasures in those countries, of which see Deuteronomy 7:13, Deuteronomy 28:40,51 Jud 9:9 Micah 5:15, &c.; and partly to show that his providence reached not only to necessaries, but even to matters of just and lawful delight.
