Commentators cannot be said to have been very successful in their attempts to trace a connection between the proverbs of this chapter. Perhaps nothing better can be said than that the common theme of these proverbs is the advantage of wisdom, and here in particular of caution in great enterprises. It is forcing the connection to imagine that the enterprise from which the writer seeks to dissuade, is that of rebellion against the ruler whose error is condemned (Ecclesiastes 10:5).
Diggeth a pit. — See Proverbs 26:27; Sir. 27:26. The word here used for “pit” is found in later Hebrew, and nowhere else in the Old Testament.
An hedge. — Rather, a stone wall, in the crevices of which serpents often have their habitation. (Comp. Proverbs 24:31; Lamentations 3:9; Amos 5:19.) This verse admits of a curious verbal comparison with Isaiah 58:12, “builder of the breach,” in one, answering to “breacher of the building” in the other.
