Ecclesiastes 10:14

Is full. Literally, “multiplies.” He babbles about anything and everything, with no knowledge of the topics on which he speaks (see 1 Tim. 1:7).

A man. That is, one who hears the fool discoursing. It is often difficult to understand, not only what the fool means, but even what he says. In all probability the more foolish a man is, the more he will be inclined to make dogmatic statements in regard to the deepest mysteries.
