13:1-6 The design of Christ in giving himself for us, is, that he may purchase to himself a peculiar people, zealous of good works; and true religion is the strongest bond of friendship. Here are earnest exhortations to several Christian duties, especially contentment. The sin opposed to this grace and duty is covetousness, an over-eager desire for the wealth of this world, with envy of those who have more than ourselves. Having treasures in heaven, we may be content with mean things here. Those who cannot be so, would not be content though God raised their condition. Adam was in paradise, yet not contented; some angels in heaven were not contented; but the apostle Paul, though abased and empty, had learned in every state, in any state, to be content. Christians have reason to be contented with their present lot. This promise contains the sum and substance of all the promises; I will never, no, never leave thee, no, never forsake thee. In the original there are no less than five negatives put together, to confirm the promise: the true believer shall have the gracious presence of God with him, in life, at death, and for ever. Men can do nothing against God, and God can make all that men do against his people, to turn to their good.
4. is, &c.—Translate, "Let marriage be treated as honorable": as Heb 13:5 also is an exhortation.
in all—"in the case of all men": "among all." "To avoid fornication let EVERY MAN have his own wife" (1Co 7:2). Judaism and Gnosticism combined were soon about to throw discredit on marriage. The venerable Paphnutius, in the Council of Nice, quoted this verse for the justification of the married state. If one does not himself marry, he should not prevent others from doing so. Others, especially Romanists, translate, "in all things," as in Heb 13:18. But the warning being against lasciviousness, the contrast to "whoremongers and adulterers" in the parallel clause, requires the "in all" in this clause to refer to persons.
the bed undefiled—Translate, as Greek requires "undefiled" to be a predicate, not an epithet, "And let the bed be undefiled."
God will judge—Most whoremongers escape the notice of human tribunals; but God takes particular cognizance of those whom man does not punish. Gay immoralities will then be regarded in a very different light from what they are now.
