'Strength' in the Bible

And Moses stretched out his hand over the sea, and the sea returned to its strength toward the morning; and the Egyptians fled against it; and Jehovah overturned the Egyptians into the midst of the sea.

My strength and song is Jah, and he is become my salvation: This is my God, and I will glorify him; My father's God, and I will extol him.

Thou by thy mercy hast led forth the people that thou hast redeemed; Thou hast guided them by thy strength unto the abode of thy holiness.
