Say
As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.
Arcana Coelestia #8041
8041. 'And Jehovah spoke to Moses, saying' means instructions given by the Divine. This is clear from the meaning of 'speaking' and 'saying', when Jehovah talks about things of the Church that are to be observed, as instructions, dealt with in 7769, 7793, 7825, and - since Jehovah is the speaker - as instructions given by the Divine; and from the representation of 'Moses' as God's truth, dealt with in 6771, 7014, 7382. So it is that 'Jehovah spoke to Moses, saying' means instructions given by the Divine through Divine Truth.
