For, behold, I will shake mine hand upon them, and they shall be a spoil to their servants: and ye shall know that the LORD of hosts hath sent me. I will shake mine hand upon them - I will threaten first, and then stretch out my hand of judgment against them.
A spoil to their servants - To those whom they had formerly subjected to their sway. As the Babylonians to the Medes and Persians; and so of the rest in the subversion of empires.
