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.
