'Pertaining' in the Bible

Don’t you know that we will judge angels—not to mention ordinary matters?

If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.

But [like a boxer] I strictly discipline my body and make it my slave, so that, after I have preached [the gospel] to others, I myself will not somehow be disqualified [as unfit for service].
