Arcana Coelestia#7994
7994. 'And Jehovah said to Moses and Aaron' means instructions given by God's truth. This is clear from the meaning of 'Jehovah said', when the statutes of the Church are the subject, as giving instructions, dealt with in 7186, 7267, 7304, 7380, 7517, 7769, 7793, 7825; and from the representation of 'Moses and Aaron' as God's truth, 'Moses' being internal truth and 'Aaron' external truth, dealt with in 7009, 7010, 7089, 7382.
Arcana Coelestia#7010
7010. 'And you will be for him as a god' means Divine Truth that goes forth directly from the Lord. This is clear from the representation of 'Moses' as the Lord in respect of Divine Truth, dealt with in 6752. Its being the Divine Truth which goes forth directly from the Lord is what is meant by the declaration that he was to be for Aaron as a god. For in the Word 'God' is used to mean the Lord with regard to Divine Truth, and 'Jehovah' to mean the Lord with regard to Divine Good.
In the Word the Lord is called 'God' when the subject is truth, but 'Jehovah' when the subject is good, see 2586, 2769, 2807, 2822, 3921 (end), 4402.
Angels are called 'gods' because of the truths from the Lord which guide them, 4402.
And in the contrary sense 'the gods of the nations' are falsities, 4402 (end), 4544.
