'Boastfully' in the Bible

Do not be boastfully ambitious and claim honor in the presence of the king,And do not stand in the place of great men;

Speak and say, ‘Thus says the Lord God,“Behold, I am against you, Pharaoh king of Egypt,The great monster that lies in the midst of his rivers,[Boastfully] declaring, ‘My Nile is my own, and I have made it for myself.’
