7209. 'And you will know that I am Jehovah your God' means the discernment then that the Lord is the only God. This is clear from the meaning of 'knowing' as discerning. One reason why 'I am Jehovah your God' means that the Lord is the only God is that by Jehovah in the Word none other than the Lord is meant, 1343, 1736, 2921, 3023, 3035, 5663, 6281, 6707, 6905. And another reason is that those in heaven know and perceive that the Lord is the Lord of heaven, and so is the Lord of the universe (even as He Himself says, in Matthew 28:18, that He has all power in heaven and on earth; in Isa 42:8, that Jehovah does not give His glory to another;a in John 14:9-11, that He is one with the Father; and in John 16:13-15, that the Holy Spirit is a holy influence which emanates from Himself) thus that the Lord is the only God.
