Wise as serpents

Jesus said that we should be wise as serpents, but how are serpents wise?

Genesis 3:1 says that the serpent was more “crafty” (ARUM) than any of the beasts of the field, and the same word is used a number of times in Proverbs, often translated as “prudent.” A crafty man conceals what he knows (12:23). The crafty man acts knowingly, not impulsively (13:16). The crafty man is not gullible but considers his steps (14:15). Crafty men see evil coming and step aside to avoid it (22:3; 27:12). A related word is used in 15:5, where the prudent accept correction. These are some ways to imitate the “craftiness” of serpents as we minister as sheep in a world of wolves (Matthew 10:16).
