Is it okay for a young man to marry an older women according to the Bible?
Yes. It is absolutely okay for a young man to marry an older women according to the bible. Many Christians and church do not know that this kind of marriages are supported in bible. They preach and teach this kind of marriages as a sin or unfair in the eyes of God and hesitate to approve such kind of marriages.
Base in the bible 1:
In Genesis 38:8, we can see that Judah asking his second son to marry Tamar, the wife of his first son. “Sleep with your brother’s wife and fulfill your duty to her as a brother-in-law to raise up offspring for your brother.”
What made you think that his second son is younger than Tamar?
I believe he is younger than Tamar because, later we can see his second son also died and he said to Tamar to wait until his third son grows up until becomes able to get married. Gen.38:11 "Then Judah said to Tamar, his daughter-in-law, "Go back to your parents' home and remain a widow until my son Shelah is old enough to marry you."
What do you think is able to get married?(Guess)
It makes it very clear that his third son was much younger than Tamar. And if Judah made such an offer, I believe it was absolutely okay to marry a women who is older and there were many who were married like that also.
Base in the bible 2:
Deuteronomy 25:5 If brothers are living together and one of them dies without a son, his widow must not marry outside the family. Her husband’s brother shall take her and marry her and fulfill the duty of a brother-in-law to her. 6 The first son she bears shall carry on the name of the dead brother so that his name will not be blotted out from Israel. 7 However, if a man does not want to marry his brother’s wife, she shall go to the elders at the town gate and say, “My husband’s brother refuses to carry on his brother’s name in Israel. He will not fulfill the duty of a brother-in-law to me.” 8 Then the elders of his town shall summon him and talk to him. If he persists in saying, “I do not want to marry her,” 9 his brother’s widow shall go up to him in the presence of the elders, take off one of his sandals, spit in his face and say, “This is what is done to the man who will not build up his brother’s family line.” 10 That man’s line shall be known in Israel as The Family of the Unsandaled.
Now, my question is, what made you think/guess that all brother in laws are elder than their sister in laws?
If the dead person is the eldest, his young brother who might be younger than his dead brother's wife is commanded to marry her and to fulfill the duty of a brother-in-law.
For all those false teachers, the following commandment given by God through Moses will be more than hard to bear because since from the time of this commandment there will be ten thousands of young men who go got married to a older women based on this commandment. And I believe if to marry a older women was not biblical, it would have been clearly specified along with that commandment.
Base in the bible 3:
Matthew 22: 24 “Teacher,” they said, “Moses told us that if a man dies without having children, his brother must marry the widow and raise up offspring for him. 25 Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. 26 The same thing happened to the second and third brother, right on down to the seventh.
My question is, How do you compare the age of this women to the age of youngest brothers? Based on various things, I assume that women is surely elder than not less than 3 or 4 of that younger brothers.
So based on these 3 strong evidences from bible, I would recommend not to prohibit marriages of older women to younger man saying that it is not supported on the basis of the bible.
