Ecclesiastes 5:9 - Joseph Benson’s Commentary on the Old and New Testaments

The profit of the earth is for all The fruits of the earth are necessary and beneficial to all men. The wise man, after some interruption, returns to his former subject, the vanity of riches; one evidence whereof he mentions in this verse, that the poor labourer enjoys the fruits of the earth as well as the greatest monarch, and that the richest man in the world depends as much upon them as the poorest. The king himself is served by the field Is supported by the fruits of the field.
