'Announcing' in the Bible

Lamech told his wives, "Adah and Zillah, listen to what I have to say: You wives of Lamech, hear what I'm announcing! I've killed a man for wounding me, a young man for bruising me.

After Moses, the servant of the LORD, had died, the LORD spoke to Nun's son Joshua, announcing to him,

"""I'm also announcing to you that the LORD also will himself build a house for you. It will come about that when your life is complete and you go to join your ancestors, I will raise up your offspring after you, who is related to one of your sons, and I will fortify his kingdom.

See, the former things have taken place, and I'm announcing the new things before they spring into being I'm telling you about them."
