Hinder not the fruit/allow exception clause

 In the beginning Yah commanded mankind to be fruitful, and multiply, and replenish the earth. Gen 1:28 

This command was never rescended, and remains in force unto this very day.

In fact Yah protects this law by making the conjugal relationship of man and wife mandatory:

Exo 21:10 KJV If he take him another wife; her food, her raiment, and her duty of marriage, shall he not diminish.

H5772

BDB Definition:

1. cohabitation, conjugal rights

TWOT entry: TWOT - 1650a

Part(s) of speech: Noun Feminine

Strong's Definition: From an unused root apparently meaning to dwell together; (sexual) cohabitation: - duty of marriage.

It is a sad fact, that today a brother is given less rights in the assembly, then a woman of ancient times, causing to many to fall away.  

This command also sets the foundation for the exception clause found in Matthew:

Mat 5:32 RNKJV But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.

This word for fornication covers all sexual sins, as shown below.

However, there is one type of fornication which is being overlooked, and must be understood. Esau was also a fornicator, however, he became a fornicator by simply refusing the intimate relationship Yah had for him.

Heb 12:16 RNKJV Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.

G4205

3. a man who indulges in unlawful sexual intercourse, a fornicator

Origin: from pernemi (to sell, akin to the base of G4097)

TDNT entry: 15:39,9

Part(s) of speech: Noun Masculine

Strong's Definition: From πέρνημι pernēmi (to sell ; akin to the base of G4097); a (male) prostitute (as venal), that is, (by analogy) a debauchee (libertine): - fornicator, whoremonger.

By refusing this intimate relationship, Esau put his body up for sale, to whomever would have him.  So Esau became a fornicator well before he ever bowed down to any false god.   

Likewise, a man Who refuses his wife intimately, is as if he is selling himself on the streets, to any stranger who will pay him.

In like manner, the woman who willfully, and without cause, refuses her husband, is putting herself up for sale, to any man who will buy her.

Yah Yeshua made it plain what must be done In such cases, the refusing spouse should be put away, and the willing spouse is free to remarry, due to the law of being fruitful and multiplying.

Paul also touched on this subject, letting us all know,  refusal is fraud:

1Co 7:5 KJV Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.

In the Aramaic Peshitta below, three reasons are given for making an agreed time of separation, short.  They are:

1. Pleasure

2. Desire of your bodies

3. lest the enemy tempt you

1Co 7:5 AEIB לא S10878 not הכיל S5185 therefore תגלזון S3816 deprive you חד S6244 one לחד S6250 another אלא S892 except אמתי S1351 when דתריכון S22993 you both תשתוון S20829 you will agree בזבן S5479 in a time דתתענון S15994 which you devote לצומא S17650 to fasting ולצלותא S17764 and to prayer ותוב S22722 and again לה S10843 to it לצבותא S17522 * to pleasure תתפנון S16832 you shall return דלא S10863 lest ננסיכון S13233 tempt you סטנא S14215 Satan מטל S11636 because of רגתא S19350 * the desire דפגרכון S16409 of your bodies

It is never the will of Yah for a man to stay in an unfruitful relationship.  However, Yah Yeshua also hates divorce.   So we pray for a repaired, fruitful relationships, for all believers in Yah Yeshua.
