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.
Arcana Coelestia#7380
7380. 'And Jehovah said to Moses' means instruction. This is clear from the meaning of 'saying' as instruction, dealt with in 7186, 7304. What is meant by the verb 'say' when used in the historical narratives of the Word is evident from what comes after it, for whatever follows goes together with it. The reason why at this point it means instruction is that Jehovah says what further things had to be done. Also 'Moses' represents the law of God, through which instruction is given by Jehovah.
