The wisdom of the prudent is to understand his way: but the folly of fools is deceit.
– Proverbs 14:8
[W]isdom is to understand, which means to separate mentally. The prudent shows wisdom in examining his way. He considers well and chooses carefully his way (Proverbs 2:9; 14:15). The word for deceit means a fraud or treachery. This is the way of fools (Proverbs 11:18). They search for short-cuts and back doors. They are quick to use deceit to gain their ends, so they go in a false way.
