Declare
To "declare" means to say something formally, publicly and with emphasis; you might say what you think, but you only declare things you're sure of. So just as saying relates to sharing truth at various levels, "declaring" relates to sharing fundamental, unquestioned principles, often those that reveal the Lord and the salvation that lies in His embrace.
In Amos 4:12-13, 'to declare' signifies to flow in.

Amos 4:12-13
12
"Therefore thus will I do to you, Israel; because I will do this to you, prepare to meet your God, Israel.
13
For, behold, he who forms the mountains, and creates the wind, and declares to man what is his thought; who makes the morning darkness, and treads on the high places of the Earth: Yahweh, the God of Armies, is his name."
