'Strength' in the Bible

From the daughter of Zion all her majesty is departed: her princes are become like harts that find no pasture, they are gone without strength before the pursuer.

The yoke of my transgressions is bound by his hand; They are knit together, they are come up on my neck; he has made my strength to fail: The Lord has delivered me into their hands, against whom I am not able to stand.

I said, My strength is perished, and my expectation from Yahweh.
