Protected by discretion

Proverbs 2:11-12 NKJV [11] Discretion will preserve you; Understanding will keep you, [12] To deliver you from the way of evil, From the man who speaks perverse things," 

Just like wisdom, knowledge and understanding are profitable. Discretion too is profitable. In fact, wisdom is usually used as a synonym of discretion.  However, in simple terms discretion is more like common sense, having the wisdom to know what to say when,  to whom to say  or what to do, when to do and how to do but it mainly deals with speech. 

We ought to know the right things to say at a particular moment and our actions will be guided. Take an example of Joseph at that moment when Portiphar's  wife wanted him to sin. Because Joseph was discreet, his actions were guided rightly. In that sense, we see that it was discretion that protected him from the evil, Genesis 39. 

In case you are someone who always speaks and people end up being turned off with your words because you've hurt their feelings then you ought to pray and ask God for for discretion. That is why the Bible says let your speech be seasoned with salt, that is discretion God was talking about here.

Colossians 4:6

And it came to pass about this time, that [Joseph] went into the house to do his business; and [there was] none of the men of the house there within. And she caught him by his garment, saying, Lie with me: and he left his garment in her hand, and fled, and got him out.
