'Strength' in the Bible

Jeroboam never recovered his strength for the rest of Abijah's life. The LORD struck Jeroboam, and he died,

"LORD God of our ancestors, you are the God who lives in heaven, are you not? You rule over all the kingdoms of the nations, don't you? In your own hands you grasp both strength and power, don't you? As a result, no one can oppose you, can they? You are our God, who expelled the former inhabitants of this land right in front of our people Israel, aren't you? Then you gave it to your friend Abraham's descendant forever, didn't you?

Our God, you are going to punish them, aren't you? We have no strength to face this vast multitude that has come against us, nor do we know what to do, except that our eyes are on you."

He only has the strength of his own flesh, but the LORD our God is with us to help us and to fight our battles." So the people were encouraged from what King Hezekiah of Judah told them.
