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.

In Exodus 7:7, eighty signifies the state and quality of the Law, since it applies to Moses. Also, 80, like 40, can represent a state of temptation, when we face and battle our desires for evil – and that it can also be looked at as the product of eight and 10, combining the meanings of those two numbers. Eight generally represents a beginning state (the eighth day is the first of a new week) and 10 can represent either a state of fullness or what are called "remains" – true ideas and desires for good implanted deep within us by the Lord in infancy, which can react with other good and truths as we grow. See Arcana Coelestia 7284.
