'Confidently' in the Bible

You will report to Amariah the chief priest in all matters pertaining to the Lord's law, and to Zebadiah son of Ishmael, the leader of the family of Judah, in all matters pertaining to the king. The Levites will serve as officials before you. Confidently carry out your duties! May the Lord be with those who do well!"

Wait patiently for the Lord! Wait confidently for him! Do not fret over the apparent success of a sinner, a man who carries out wicked schemes!

Your very best valleys were full of chariots; horsemen confidently took their positions at the gate.

Who is this who comes from Edom, dressed in bright red, coming from Bozrah? Who is this one wearing royal attire, who marches confidently because of his great strength? "It is I, the one who announces vindication, and who is able to deliver!"
