Jehovah
Now therefore make confession unto the LORD God of your fathers, and do his pleasure: and separate yourselves from the people of the land, and from the strange wives. Ezra 10:11
Repentance begins with confessing to Jehovah, the God of their fathers, who is the premortal Jesus Christ, and then doing His will.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
