Jehovah
Therefore thus saith the Lord GOD; Because thou hast forgotten me, and cast me behind thy back, therefore bear thou also thy lewdness and thy whoredoms. Ezekiel 23:35
The whole allegory pictures Israel as a wife who belonged to the LORD (verse 4: 'they were mine') and then left Him. Latter-day Saints understand this covenant Husband, Jehovah, to be the premortal Jesus Christ. Being unfaithful to the covenant means forgetting Him and turning your back on Him.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
