'Proclaim' in the Bible

Then they must proclaim, "Our hands have not spilled this blood, nor have we witnessed the crime.

It is not in heaven, as though one must say, "Who will go up to heaven to get it for us and proclaim it to us so we may obey it?"

And it is not across the sea, as though one must say, "Who will cross over to the other side of the sea and get it for us and proclaim it to us so we may obey it?"

For I will proclaim the name of the Lord; you must acknowledge the greatness of our God.
