'Confidently' in the Bible

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

“You will keep in perfect and constant peace the one whose mind is steadfast [that is, committed and focused on You—in both inclination and character],Because he trusts and takes refuge in You [with hope and confident expectation].

“Trust [confidently] in the Lord forever [He is your fortress, your shield, your banner],For the Lord God is an everlasting Rock [the Rock of Ages].

And now, hear this, O luxurious one, Who is sitting confidently -- Who is saying in her heart, 'I am, and none else, I sit not a widow, nor know bereavement.'

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!"
