Job 31:14

They had observed some of His disciples eating their food with contaminated, that is, [ceremonially] unwashed hands.

For the person who has shown no mercy will be judged without mercy. [For] mercy wins out over condemnation.

Now we [all] know that everything the law says applies to those who are under [obligation to obey] that law, [Note: Here "the law" appears to refer to the Old Testament Scriptures generally, since Psalms and Isaiah are quoted. See verses 10-18]. This is so that the mouth of every objector may be stopped [i.e., from making excuses for his sin], and thereby bring the entire world under God's judgment [i.e., both Jews and Gentiles].
