Verses 1–4
Divorce and a Certificate of Divorce
It seems that this arrangement is being made because divorce is already regularly happening. Possibly it has even been practiced in Egypt. The purpose of this prescript seems to be to discourage a loose divorce. If someone has sent his wife out of his house and she is married again and is then send away again, then the first man is not allowed to take her back as his wife.
Although God, because of the hardness of their hearts, has allowed them to send their wives away, He considers the next marriage of the woman to be defiled. Therefore the Lord Jesus says that anyone who marries a woman who is send away by her husband commits adultery. This could not be so if God were to recognize divorce as a lawful thing. But for God there can be no legitimate reason for divorce.
There is no explicit consent to divorce anywhere. It is permitted, because of the hardness of heart (Matthew 19:8). God hates divorce (Malachi 2:16). This arrangement is also made to prevent a man from always acting according to will, at his discretion. He could change women as often as he likes. What a confusion that would cause in family life. Finally, there would also be no clarity about the inheritance.
The reason for sending away can be anything the man describes as “some indecency”. In any case, it has nothing to do with adultery, because therefore death penalty applies (Deuteronomy 22:20-Song of Solomon :). If he sends the wife away, he must give a certificate of divorce. She then has proof that her first husband renounces her and is no longer allowed to take her to wife.
God has given Israel a certificate of divorce: “And I saw that for all the adulteries of faithless Israel, I had sent her away and given her a writ of divorce” (Jeremiah 3:8). How long did God not hesitate before He gave that letter? Finally, God had to write the certificate of divorce, because it is an apostate people who, as it is, will never return to blessing. For the people as a whole there is no recovery. What is being restored is a remnant of the election of grace (Romans 11:5; Romans 11:23-Jeremiah :). Grace goes beyond the law. In this remnant God accepts His people again, while they as a whole have been whoring away from Him.
For the church as nominal Christianity, the moment of the certificate of divorce also comes. No restoration is possible for this Christianity either (Revelation 18:21; Romans 11:21-Song of Solomon :). However, in the present time there is still a Philadelphia (Revelation 3:7-1 Chronicles :). This is indicated in Deuteronomy 24:5.
