'Boaster' in the Bible

Terrify him do adversity and distress, They prevail over him As a king ready for a boaster.

But -- in this let the boaster boast himself, In understanding and knowing Me, For I am Jehovah, doing kindness, Judgment, and righteousness, in the earth, For in these I have delighted, An affirmation of Jehovah.

When I talk as a confident boaster, I am not talking with the Lord's authority but like a fool.

But, idle boaster, are you willing to be taught how it is that faith apart from obedience is worthless? Take the case of Abraham our forefather.
