Hebrews
King James Version (KJV)

“Pray for us: for we trust we have a good conscience, in all things willing to live honestly.”
King James Version (KJV)
13:17 Obey them that have the rule over you - The word implies also, that lead or guide you; namely, in truth and holiness. And submit yourselves - Give up (not your conscience or judgment, but) your own will, in all things purely indifferent. For they watch over your souls - With all zeal and diligence, they guard and caution you against all danger. As they that must give account - To the great Shepherd, for every part of their behaviour toward you. How vigilant then ought every pastor to be! How careful of every soul committed to his charge! That they may do this - Watch over you. With joy and not with groans - He is not a good shepherd, who does not either rejoice over them, or groan for them. The groans of other creatures are heard: how much more shall these come up in the ears of God ! Whoever answers this character of a Christian pastor may undoubtedly demand this obedience.
13:20 The everlasting covenant - The Christian covenant, which is not temporary, like the Jewish, but designed to remain for ever. By the application of that blood, by which this covenant was established, may he make you, in every respect, inwardly and outwardly holy!
Heb 13:18 Pray for us. Paul often makes this request. See PNT "1Th 5:25". For we trust we have a good conscience, in all things willing to live honestly. He refers to his uprightness of life perhaps because he had been arrested as an evil doer in Jerusalem (Ac 21:33 24:5).
