But he that doeth wrong - It is possible for an unfaithful servant to wrong and defraud his master in a great variety of ways without being detected; but let all such remember what is here said: He that doeth wrong shall receive for the wrong which he has done; God sees him, and will punish him for his breach of honesty and trust. Wasting, or not taking proper care of the goods of your master, is such a wrong as God will resent. He that is unfaithful in that which is little, will be unfaithful in much, if he have opportunity; and God alone is the defense against an unfaithful servant.
There is no respect - God neither esteems nor despises any man because of his outward condition and circumstances; for there is no respect of persons with him. Every man is, in the eye of God, what he is in his soul: if holy, loved; if wicked, despised and rejected.

(15) But he that doeth wrong shall receive for the wrong which he hath done: and there is no respect of persons.
(15) He requires of masters, that being mindful how they themselves also will render an account before that heavenly Lord and Master, who will avenge wrongful deeds without any respect of masters or servants, they show themselves just and upright with fairness to their servants.

But he that doth wrong,.... Which may be understood, both of servants that do wrong to their masters through sloth and idleness, neglecting their business, embezzling their masters' goods, and defrauding them of their substance; and of masters that injure their servants by withholding from them proper food, and raiment; by cheating them of their wages, either giving them none at all, or too little, or detaining them too long, and by giving them bad language, and hard blows, and such like severe usage:
shall receive for the wrong which he hath done; either in this world, or in the other; God will avenge all such injuries, sooner or later; so that these words may be considered either as said with a view to deter servants from evil practices, or to comfort them under the maltreatment they may meet with from cruel masters:
and there is no respect of persons. The Vulgate Latin and Arabic Versions add, "with God"; which undoubtedly is the sense; he regards not the rich more than the poor; he makes no difference between bond and free, the servant and the master; he will not take the part of the one, because he is a master, nor neglect, the other, because he is a servant, but will do that which is just and right with regard to them both; See Gill on Ephesians 6:9.

But--The oldest manuscripts read, "for," which accords with "serve ye," &c. (Colossians 3:24), the oldest reading: the for here gives a motive for obeying the precept. He addresses the slaves: Serve ye the Lord Christ, and leave your wrongs in His hands to put to rights: (translate), "For he that doeth wrong shall receive back the wrong which he hath done (by just retribution in kind), and there is no respect of persons" with the Great Judge in the day of the Lord. He favors the master no more than the slave (Revelation 6:15).
