Isaiah 13:17
17Behold, I will stir up the Medes against them, who will not value silver, and as for gold, they will not delight in it.
Wesley: Medes—under whom he comprehends the Persians. Not delight—which is to be understood comparatively. They shall more eagerly pursue the destruction of the people than the getting of spoil. Tho’ the Medes had no regard to God, but only to their own ends.
God stirs up the Medes, yet they pursue their own campaign; silver and gold will not buy them off. The warning was spoken over Babylon at the height of its power, while there was still time to fear.
Calvin: Behold I raise up against them the Medes. He could not have conjectured this by human reason. Who shall not think of silver, nor desire gold: not that they were innocent of plunder, but that the battle will be cruel and bloody, aimed at a general slaughter. The Lord, though he is not cruel, makes use of agents who are so cruel; he acts righteously even by the agency of wicked men.
The LORD stirs the Medes. Pagan hunger for slaughter still serves his indignation. The stirring is his decree against Babylon.
Key contrast Both hear God stirring the Medes against Babylon, not a modern map. Arminians typically follow Wesley’s “own ends”—comparatively they hunt destruction more than spoil, and still the warning stood. Reformed interpreters side with Calvin’s further word: the LORD raises them; he is not stained by their cruelty, and the battle is his.
