10537. 'And Jehovah said to Moses' means instruction. This is clear from the meaning of 'saying', when Jehovah is the speaker, as instruction, dealt with in the places referred to in 10280, at this point instruction showing that Divine Truth did not reside with the actual nation, which is meant by the command to them to take off their finery, dealt with below.

6879. 'And God said to Moses' means the instruction that is provided first. This is clear from the meaning of 'God's saying', at this point His saying to Moses (who represents the Lord in respect of Divine Truth) and His saying through Moses to the people (that is, speaking through the Divine Truth going forth from the Lord's Divine Human to those who belong to the spiritual Church) as instruction, in this case the instruction that is provided first since the true God who is to be worshipped is the subject. For the first feature of the Church is that God exists and that He is to be worshipped. The first thing about Him that one should know is that He has created all things and that every created thing is kept in being by Him.
