'Strengthen' in the Bible

"When that day comes about, I'll strengthen Israel's military might, and I will give you an audience in their midst. Then they will know that I am the LORD.'"

I'm going to strengthen the military might of the king of Babylon, put my own sword in his hand, and break Pharaoh's strength. Then Pharaoh will groan like a dying man right in front of the king of Babylon.

When I strengthen the military might of Babylon, the military might of Pharaoh will fail, and then they will learn that I am the LORD when I place my own sword in the hand of the king of Babylon. He will attack the land of Egypt.
