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.

6881. 'And He said, Thus shall you say to the children of Israel' means the instruction that is provided second. This is clear from the meaning of 'God said', when it is used a second time, as a new phase of perception, dealt with in 2061, 2238, 2260, the new phase of perception being here the instruction that is given second; and from the representation of 'the children of Israel' as those who belong to the spiritual Church, for whose benefit that instruction was provided.
