'Strength' in the Bible

Absalom sent for Ahithophel the Gilonite, the advisor of David, from his city Giloh, while he offered the sacrifices. The conspiracy {grew in strength}, and the people [were] going and {increasing} with Absalom.

I take refuge in God, my rock, my shield, and the {strength} of my salvation. My stronghold and my refuge, O my savior, you will save me from violence!

You have girded me with physical strength for the battle; you caused those who rose up against me to kneel under me.
