Proverbs 7:5 KJV — That they may keep thee from the strange woman, from the stranger which flattereth with her words.
“They” is wisdom and understanding.
They will keep you from the strange woman, from that which lies outside of the new covenant you have in Jesus.
They keep you through the way you see things. The things you don’t do or don’t get round to doing because you don’t see it or because you’re busy seeing other things.
You don’t get round to watching that series because you’re busy writing your own.
You don’t go out to that late night party because you need to get a full night’s sleep.
The restraints and constraints of wisdom and understanding keep you safe.
