'Confident' in the Bible

Behold, if a river overflow, he trembleth not; He is confident, though a Jordan swell even to his mouth.

Though a host should encamp against me, My heart shall not fear: Though war should rise against me, Even then will I be confident.

A wise man feareth, and departeth from evil; But the fool beareth himself insolently, and is confident.

and art confident that thou thyself art a guide of the blind, a light of them that are in darkness,

being confident of this very thing, that he who began a good work in you will perfect it until the day of Jesus Christ:

and that most of the brethren in the Lord, being confident through my bonds, are more abundantly bold to speak the word of God without fear.
