'Strength' in the Bible

Yahweh, my strength, and my stronghold, and my refuge in the day of affliction, to you shall the nations come from the ends of the earth, and shall say, Our fathers have inherited nothing but lies, [even] vanity and things in which there is no profit.

Those who fled stand without strength under the shadow of Heshbon; for a fire is gone forth out of Heshbon, and a flame from the midst of Sihon, and has devoured the corner of Moab, and the crown of the head of the tumultuous ones.

Though Babylon should mount up to the sky, and though she should fortify the height of her strength, yet from me shall destroyers come to her, says Yahweh.
