But I say to you places the declaration of Jesus in contrast to that of the Old Testament; this is the same formula used in verse 22.

The text has every one, but it is often more natural to say “anyone” or “whoever.”

Unchastity (so also New English Bible, Moffatt, Translator’s New Testament) was translated “fornication” by Jerusalem Bible and “lewd conduct” by New American Bible, since the Greek word may refer to any illicit sexual relations, although it would be assumed to mean adultery here. Good News Translation, An American Translation, and Phillips have “unfaithfulness” (Die Bibel im heutigen Deutsch “unfaithful”). However, sociological studies of New Testament times have led some scholars to suggest that a better rendering would be “an unlawful marriage,” as for example between people of certain blood or legal relationships who were forbidden to marry each other by Mosaic Law. New Jerusalem Bible and Traduction œcuménique de la Bible, for example, have “except for the case of an illicit marriage,” and the revised New Testament of New American Bible has “unless the marriage is unlawful.”

Translations which follow the first interpretation can have “unless she had committed adultery,” “unless she had been unfaithful,” or “unless she had slept with other men.” Those who follow the second will have a sentence similar to New Jerusalem Bible, Traduction œcuménique de la Bible, or revised New American Bible, cited above.

In many languages, translators have to restructure this sentence slightly to cover the meaning of except. Examples are “anyone who divorces his wife for any reason except…” or “anyone who divorces his wife, but the reason was not because she….”

The Old Testament commandment allowing for a bill of divorce to be given accepted divorce as legitimate. However, Jesus is denying this by saying that unless the marriage was illegal (or possibly unless the woman had been unfaithful), then the divorce is not legal, and the woman is guilty of adultery if she marries again. Moreover, the assumption is that she will probably marry again. Therefore the inclusion of “if she marries again” (Good News Translation, Bible en français courant, Bibel im heutigen Deutsch, 1st edition, Bijbel in Gewone Taal) is necessary for the reader; otherwise the point of what Jesus is saying will be missed completely.

To say he makes her an adulteress means that “he makes her guilty of adultery” or “he is the one responsible for making her commit adultery.” Since this will only be the case if she marries again, something in the possible future, then translators can say “then if she marries again, he is the one responsible for her committing adultery in that way” or “when she remarries and in doing so becomes guilty of adultery, then he is the one who has caused this adultery.”

And whoever marries a divorced woman commits adultery is also based on the logic that in principle—though not legally—the divorced woman is still married to her first husband. Some Greek manuscripts omit this clause. But the UBS Greek New Testament favors the opinion that its omission is due to the overzealousness of certain scribes who may have regarded these words as unnecessary in light of the previous statement, makes her an adulteress (so TC-GNT).

The last clause can be expressed as “the man who marries a divorced woman is committing adultery” or “it is adultery also for the man if he marries a divorced woman.”
