'Matter' in the Bible

But I say to you that everyone who divorces his wife, except for a matter of sexual immorality, causes her to commit adultery, and whoever marries a divorced woman commits adultery.

But if he does not listen, take with you in addition one or two [others], so that by {the testimony} of two or three witnesses every matter may be established.

Again, truly I say to you that if two of you agree on earth about any matter that they ask, it will be done for them from my Father [who is] in heaven.

And if this [matter] is heard before the governor, we will satisfy him and {keep you out of trouble}."
