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.
Zechariah 13:8-9
8
It shall happen that in all the land," says Yahweh, "two parts in it will be cut off and die; but the third will be left in it.
9
I will bring the third part into the fire, and will refine them as silver is refined, and will test them like gold is tested. They will call on my name, and I will hear them. I will say, 'It is my people;' and they will say, 'Yahweh is my God.'"
