If you are seriously in search of the truth about marriage then this article is for you, get your Bible out!
I mainly will be giving the book and chapter I am quoting in hopes it will cause you to read more than just the verses I provided, so please STUDY YOUR BIBLE!

Let's begin in the Old Testament on this subject.

The Jews held to two different paths of thought on this:
Hillel - believed a man could divorce his wife for ANY reason
Shmmai - could only divorce only for adultery

Both were referencing to Deuteronomy with "uncleanness" and depending on which group you looked at believed it in 2 different views with the Shmmai believing it meant adultery while the Hillel thought it meant for any unclean reason.

Deuteronomy chapter 24:
When a man hath taken a wife, and married her, and it come to pass that she find no favour in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give [it] in her hand, and send her out of his house.
And when she is departed out of his house, she may go and be another man's [wife].
And [if] the latter husband hate her, and write her a bill of divorcement, and giveth [it] in her hand, and sendeth her out of his house; or if the latter husband die, which took her [to be] his wife;
Her former husband, which sent her away, may not take her again to be his wife, after that she is defiled; for that [is] abomination before the LORD: and thou shalt not cause the land to sin, which the LORD thy God giveth thee [for] an inheritance.
When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: [but] he shall be free at home one year, and shall cheer up his wife which he hath taken."

Ezra chapter 10:
And Ezra the priest stood up, and said unto them, Ye have transgressed, and have taken strange wives, to increase the trespass of Israel.
Now therefore make confession unto the LORD God of your fathers, and do his pleasure: and separate yourselves from the people of the land, and from the strange wives.
Then all the congregation answered and said with a loud voice, As thou hast said, so must we do.

Malachi chapter 2:
Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.
For the LORD, the God of Israel, saith that he hateth putting away: for [one] covereth violence with his garment, saith the LORD of hosts: therefore take heed to your spirit, that ye deal not treacherously.

Now with that in mind, let's have a look at how God originally instituted marriage in Genesis chapter 2
And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;
And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.
And Adam said, This [is] now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh."

Matthew chapter 19:
They say unto him, Why did Moses then command to give a writing of divorcement, and to put her away?
He saith unto them, Moses because of the hardness of your hearts suffered you to put away your wives: but from the beginning it was not so.
And I say unto you, Whosoever shall put away his wife, except [it be] for fornication, and shall marry another, committeth adultery: and whoso marrieth her which is put away doth commit adultery.

In Matthew 19 we read that Jesus Christ essentially rebuked Moses for going against the will of God to forebear the hardness of their hearts.
  Now many will say they can remarry after divorcement and like using what Paul said in 1 Corinthians chapter 7  to justify their adultery.
9 But if they cannot contain, let them marry: for it is better to marry than to burn.
and ignore the context of whom this is given unto but if we look in verse 8 we read
8 I say therefore to the unmarried and widows, It is good for them if they abide even as I.
9 But if they cannot contain, let them marry: for it is better to marry than to burn.
The context for verse 9 is to the UNMARRIED AND WIDOWS, not those that have divorced/been put away.
Verses 10 and 11 say
And unto the married I command, [yet] not I, but the Lord, Let not the wife depart from [her] husband:
But and if she depart, let her remain unmarried, or be reconciled to [her] husband: and let not the husband put away [his] wife.
Remarriage was not permitted, but rather reconciliation was prescribed or rather FORGIVENESS. 

Then Paul went on to say
But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away.
And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him.
For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.
But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such [cases]: but God hath called us to peace. Wives love your husbands Titus 2:4 "...to love their husbands"

1 Peter chapter 3
For after this manner in the old time the holy women also, who trusted in God, adorned themselves, being in subjection unto their own husbands:
Even as Sara obeyed Abraham, calling him lord: whose daughters ye are, as long as ye do well, and are not afraid with any amazement.
Likewise, ye husbands, dwell with [them] according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.
Finally, [be ye] all of one mind, having compassion one of another, love as brethren, [be] pitiful, [be] courteous:
Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.

Ephesians chapter 5 we read:
Therefore as the church is subject unto Christ, so [let] the wives [be] to their own husbands in every thing.
Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
For we are members of his body, of his flesh, and of his bones.
For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
Nevertheless let every one of you in particular so love his wife even as himself; and the wife [see] that she reverence [her] husband. This is an on going study but I wanted to go ahead and post some of the work I have done, please come back in Jan 2020 and this article should be completed!
