Forsake the foolish, and live; and go in the way of understanding.
– Proverbs 9:6
Any true call to wisdom necessarily means a departing from that that is not wisdom. The foolish, or the simple ones, are not fit companions and coming to wisdom means leaving their company. This is consistent in the call to wisdom throughout Proverbs (Proverbs 4:14-15; 13:20). Turning to understanding, i.e. discernment, is a turning into the way, which is a road put here for course of life. It is not momentary or isolated. It is a change of life.
