Since there was (an in-law) kinship involved, marriage to Ruth was part of the process of redeeming a certain relative's field. This was considered a righteous thing (Leviticus ch.25). Though not a brother in-law, nonetheless a certain form of levirate marriage was also involved, which is also the right thing to do (Deuteronomy ch.25).
Also, Boaz had noticed that Ruth was very righteous.
the guy who was suppose to marry Ruth was too old and so he told boaz to marry ruth
He was second of kin to her.
As she was a widow and young and beautiful to look at he wanted to marry Ruth.
Ruth married Boaz. Rebecca married Isaac.Ruth was born around 800 years after Isaac.See:Jewish timeline
The Bible doesn't mention that at all.
No she did not sin, as she was a widow she could marry him.
To redeem the land and marry Ruth all Boaz had to do was to buy the land, as Ruth was part of the package deal. Because the land was an inheritance which belonged to her husband and his wife and family, since he was dead and there were no children his wife Ruth was the rightful heir.
Obed is the only son of Ruth and Boaz, it is in Ruth chapter4.
The main characters in the Book of Ruth are Ruth, Naomi, Boaz, and Obed. Ruth is a Moabite woman who becomes a widow and follows her mother-in-law, Naomi, back to Bethlehem. There, she meets Boaz, a wealthy landowner, and they eventually marry and have a son named Obed.
Boaz was Naomi's relative through her deceased husband's family. He was a kinsman-redeemer who had the right to marry Ruth, Naomi's daughter-in-law, and redeem the family property.
Fom the line of Ruth and Boaz.
It is not the Hollywood love model ... There is a commandment which says that you have to marry , your brother's widow if he did not had sons , and so did Boaz ... Ruth and Naomi went trough hard times and poverty , Ruth followed Naomi back to Israel and she converted to Judaism , then Boaz was to do his duty and marry her. Those fact/stories/principles are not on the level of love as described today .... The answer is yes and you cannot get to such details by reading the bible in eng. only the Hebrew has the "below" surface meanings in the writings.
