'Boast' in the Bible

But if you call yourself a Jew and rely on the law and boast of your relationship to God

You who boast in the law dishonor God by transgressing the law!

For if Abraham was declared righteous by the works of the law, he has something to boast about -- but not before God.

do not boast over the branches. But if you boast, remember that you do not support the root, but the root supports you.

So I boast in Christ Jesus about the things that pertain to God.
