Lord of Hosts
LORD of hosts — Jehovah, commander of heaven's armies
And say unto them, Thus saith the LORD of hosts, the God of Israel; Behold, I will send and take Nebuchadrezzar the king of Babylon, my servant, and will set his throne upon these stones that I have hid; and he shall spread his royal pavilion over them. Jeremiah 43:10–12
Jehovah, the premortal Christ, rules over the nations and even uses a pagan king as His tool against Egypt's false gods. (Here "my servant" means Nebuchadrezzar, not the Messiah.)

How we know: the verse itself names Him
