'Brag' in the Bible

If Abraham was justified by works, he has something to brag about—but not before God.

do not brag that you are better than those branches. But if you do brag—you do not sustain the root, but the root sustains you.

For I know your eagerness, and I brag about you to the Macedonians: “Achaia has been prepared since last year,” and your zeal has stirred up most of them.

But if you have bitter envy and selfish ambition in your heart, don’t brag and deny the truth.
