'Unless' in the Bible

Of such a one I will boast, but of myself I will not boast, unless in my weaknesses.

For in what is it that ye have been inferior to the other assemblies, unless that I myself have not been in laziness a charge upon you? Forgive me this injury.

Test yourselves to see if you are in the faith. Examine yourselves. Or do you yourselves not recognize that Jesus Christ is in you?—unless you fail the test.
