He shall judge among the heathen - Among the “nations.” That is, he shall set up a kingdom, or shall rule over the nations of the earth. He shall come to execute judgment and justice, and shall apportion to people what is due to them. See the notes at Isaiah 11:3-5.
He shall fill the places with the dead bodies - He shall make a great slaughter - indicative of conquest, and of the subjugation of the world to himself. It would be “as if” the bodies of the slain in battle strewed the ground, or filled the valleys of the earth.
He shall wound the heads - The same word is used here that occurs in the previous verse, and that is there rendered “shall strike.” It is the language of “conquest,” as if the world was to be subdued to himself by war.
Over many countries - Margin, “great.” Over vast and extensive regions, carrying his conquests into distant lands. This will be fulfilled only when all the earth shall be subject to the reign of the Messiah. 1 Corinthians 15:24-28.
