19 Dearely beloued, auenge not your selues, but rather giue place vnto wrath: for it is written, Uengeance is mine, I will repay, saith the Lord.
2,3. God is that one who keepeth.
There is a difference between wrath and determination and vengeance, and self and family protection. Often the Lord uses your actions to "keep" those that He wants kept.
