Ezekiel 32:24,25

“There is Elam and all her multitude round about her grave. All of them slain, fallen by the sword, who are gone down uncircumcised into the nether parts of the earth, who caused their terror in the land of the living, and have borne their shame with those who go down to the pit. They have prepared her a bed in the midst of the slain with all her multitude. Her graves are round about her, all of them uncircumcised, slain by the sword. For their terror was caused in the land of the living, and they have borne their shame with those who go down to the pit. He is put in the midst of those who are slain.”

Elam were an ancient people east of Babylon, known for their warlikeness and had been part of the Assyrian empire. They were probably prominent as bowmen in assisting the Assyrians against Israel for Jeremiah calls down judgment on them (Jeremiah 49:34). They survived better than Assyria the effects of the Babylonian invasion and were later strong enough to assist Cyrus in defeating Babylon. But they too had spread terror along with the Assyrians, and had suffered at the hands of Nebuchadnezzar's armies. Effectively that generation of Elam had joined Assyria in the world of the dead.
