A good example of “divine investiture” is the following passage from Deuteronomy where Moses speaks as if he was YHWH:
Moses summoned all Israel and said to them: You have seen all that the Lord did before your very eyes in the land of Egypt, to Pharaoh and to all his courtiers and to his whole country: the wondrous feats that you saw with your own eyes, those prodigious signs and marvels . . . you had no bread to eat and no wine or other intoxicant to drink--that you might know that I the Lord am your God. When you reached this place, King Sihon of Heshbon and King Og of Bashan came out to engage us in battle, but we defeated him. (Deut 29:1-2, 5-6 | JPS 1985 Tanakh)
