'Due' in the Bible

There he met a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife, Priscilla, because [the Roman Emperor] Claudius had issued an edict that all the Jews were to leave Rome. Paul went to see them,

serving the Lord with all humility and with tears and trials which came on me because of the plots of the Jews [against me];

solemnly [and wholeheartedly] testifying to both Jews and Greeks, urging them to turn in repentance to God and [to have] faith in our Lord Jesus Christ [for salvation].
