But the Lord is faithful, who will establish you, and guard you from the evil one.
who shall stablish you: "Stablish" (steerizo) means "to strengthen, make firm;...to render constant, confirm, one’s mind (A.V. establish)" (Thayer 588-1-4741). Among the many things that God is faithful to do is to establish us by keeping us firm. He will never allow us to be tempted with more than we can bear (1 Corinthians 10:13).
