knoweth not how to go to the city - proverb for ignorance of the most ordinary matters (Ecc 10:3); spiritually, the heavenly city (Psa 107:7; Mat 7:13, Mat 7:14). Maurer connects Ecc 10:15 with the following verses. The labor (vexation) caused by the foolish (injurious princes, Ecc 10:4-7) harasses him who “knows not how to go to the city,” to ingratiate himself with them there. English Version is simpler.
