I will strengthen the arms of the king of Babylon, but the arms of Pharaoh will fall limp. Then they will know that I am the LORD, when I put my sword into the hand of the king of Babylon and he brandishes it against Egypt.
NIV
But I will strengthen and hold up the arms of the king of Babylon and the arms of Pharaoh shall fall down, and they [of Egypt] shall know (understand and realize) that I am the Lord [the Sovereign Ruler, Who calls forth loyalty and obedient service], when I put My sword into the hand of the king of Babylon and he shall stretch it out upon the land of Egypt.
AMP
But I will strengthen the arms of the king of Babylon, and the arms of Pharaoh shall fall down; and they shall know that I am the LORD, when I shall put my sword into the hand of the king of Babylon, and he shall stretch it out upon the land of Egypt.
