Jehovah
Thus saith the LORD God of Israel; Behold, I will turn back the weapons of war that are in your hands, wherewith ye fight against the king of Babylon, and against the Chaldeans, which besiege you without the walls, and I will assemble them into the midst of this city. Jeremiah 21:4–5
The LORD God of Israel, the premortal Christ, speaks through Jeremiah. The 'outstretched hand' that once delivered Israel from Egypt now turns against a covenant people who rejected Him.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
