Romans 7:2

Wherefore the apostle says: "The wife is bound by the law so long as her husband liveth; but if he be dead, she is loosed from the law of her husband."

If, however, the husband shall have died, she has been freed from (his) law, (so) that she is not an adulteress if made (wife) to another husband." But read the sequel as well in order that this sense, which flatters you, may evade (your grasp).

Next, after hinting this at the commencement, he carries on what he has to say by way of proof, in the woman's case, in the following way. "For the woman which hath an husband is bound by the Law to her husband, so long as he liveth: but if the husband be dead, she is loosed from the Law of her husband. So then, if while her husband liveth, she be married to another man, she is called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man." He keeps continually upon this point, and that with great exactness, since he feels quite sure of the proof grounded on it: and in the husband's place he puts the Law, but in the woman's, all believers. Then he adds the conclusion in such way, that it does not tally with the premiss; for what the context would require would be, "and so, my brethren, the Law doth not rule over you, for it is dead." But he does not say so, but only in the premiss hinted it, and in the inference, afterwards, to prevent what he says being distasteful, he brings the woman in as dead by saying, "Wherefore, my brethren, ye also are become dead to the Law." As then the one or the other event gives rise to the same freedom, what is there to prevent his showing favor to the Law without any harm being done to the cause? "For the woman which hath an husband is bound by the Law to her husband as long as he liveth." What is become now of those that speak evil of the Law? Let them hear, how even when forced upon it, he does not bereave it of its dignity, but speaks great things of its power; if while it is alive the Jew is bound, and they are to be called adulterers who transgress it, and leave it whiles it is alive. But if they let go of it after it has died, this is not to be wondered at. […]

For he indicates this also in what follows, where he says: "While her husband lives, she is bound to the law;" and the very order of the example that has been taken up declares the same thing more fully: for he has put the law in the place of the husband, and concerning it he says: "But if her husband dies, she is loosed from the law of her husband."

Then he clarifies what he had said with an example from the law of marriage, when he says for the woman who has a husband: first, he gives the example; second, he clarifies it by a sign, at therefore, while. In regard to the first …

He hints at this at the beginning, and further on speaks of it from another side. Namely: when the husband dies, the wife has the right to join in marriage with another.

For the woman which hath an husband,....

For the woman which hath a husband - The apostle illustrates his meaning by a familiar instance. A married woman is bound to her husband while he lives; but when her husband is dead she is discharged from the law by which she was bound to him alone.

For the woman - This verse is a specific illustration of the general principle in Rom 7:1, that death dissolves those connections and relations which make law binding in life. It is a simple illustration; and if this had been kept in mind, it would have saved much of the perplexity which has been felt by many commentators, and much of their wild vagaries in endeavoring to show that “men are the wife, the law of the former husband, and Christ the new one;” or that “the old man is the wife, sinful desires the husband, sins the children.” Beza. (See Stuart.) Such expositions are sufficient to humble us, and to make us mourn over the puerile and fanciful interpretations which even wise and good people often give to the Bible. Is bound by the law ... - See the same sentiment in 1Co 7:39. To her husband - She is united to him; and is under his authority as the head of the household. To him is particularly committed the headship of the family, and the wife is subject to his law, in the Lord, Eph 5:23, Eph 5:33. She is loosed ... - The husband has no more authority. The connection from which obligation resulted is dissolved.
