Midrasch zu Ejchah 3:34

“To subdue under his feet all the prisoners of the earth” (Lamentations 3:34).
“To subdue under his feet…” – this is Nebuchadnezzar, in whose regard it is written: “[And everywhere] the sons of man, the beasts of the field, and the birds of the heavens dwell, He has given them into your hand and set your rule over all of them; you are the head of gold” (Daniel 2:38).
