Map showing the story of Ruth
The inset picture (taken from http://en.wikipedia.org/wiki/Book_of_Ruth)
beautifully depicts Ruth, the Moabite widow who chose to stay with her widowed mother-in-law , Naomi wherever she goes; while Orpah chose to stay in her native land Moab.
Referring to Footnotes Ruth* [1:1-2] Back in the time
of the judges:
According to Flavius Josephus in his Antiquity of the Jews; the story of Ruth happened just after the death of Samson, Eli the high priest was governor of the Israelites. Under him, the country was afflicted with a famine. (Josephus Flavius’ Antiquities of the Jews - Book V Chapter 9)
Bethlehem in the north mentioned in Jos 19:15 is found in the land of
Zebulun. (Joshua 19:15-16) This is different from Bethlehem of Judah which is in the south. (see map above).
The old Hebrew name bêth lehem, meaning "house of bread", has survived till the present day. In its Arabic form, however, bêt laham, it means "house of meat".
There is a very important religious significance of this as Our Lord Jesus Christ in the last supper turned the bread into His Body and the wine into His Blood and told his apostles to do this in remembrance of Him (Luke 22:14-20). Catholic priests do this every time we celebrate the Holy Sacrifice of the Mass.
Through this Sacrament of the Holy Eucharist we are admitted in what is called the Marriage Supper of the Lamb (Revelation 19:9) which is the mystical union, the marriage of Christ as the bridegroom with the Church as His bride (see Revelation 19:9; 21:9; 22:17).
This is described in the Cathechism of the Catholic Church:
1244 First Holy Communion. Having become a child of God clothed with the wedding garment, the neophyte is admitted “to the marriage supper of the Lamb”  and receives the food of the new life, the body and blood of Christ
The Eucharist is the sacramental anticipation and, in a
certain sense, a "foretaste" of that royal feast which the Book of
Revelation calls "the marriage supper of the Lamb" (cf. Rev 19:9).
The bridegroom who is at the center of that marriage feast and of its
Eucharistic foreshadowing and anticipation is the Lamb who "took away the
sins of the world," the Redeemer.
(Blessed John Paul II - The Intrinsic Link between the Eucharist and the Gift of the Holy Spirit)
“Amen, amen, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you do not have life within you.
Whoever eats my flesh and drinks my blood has eternal life, and I will raise him on the last day.
For my flesh is true food, and my blood is true drink.
Whoever eats my flesh and drinks my blood remains in me and I in him.
Just as the living Father sent me and I have life because of the Father, so also the one who feeds on me will have life because of me.
This is the bread that came down from heaven. Unlike your ancestors who ate and still died, whoever eats this bread will live forever.”
Ruth [1:1] Judah – is land of the descendants of Judah, who is the youngest son (Genesis 29:35) of Jacob who is also called Israel (Genesis 32:29) with his first wife Leah (Genesis 29:21-23). The word Judah is related to ’odeh, “I will give thanks, praise.” (Footnotes Genesis * [29:35]).
Ruth [1:1] Moab: The land
of the Moabites. The phrase “From my father” in Hebrew me’abi,
is similar in sound to the name “Moab.”
However, it can probably also mean the residents of Ephrath, which is Bethlehem.
We read in 1 Chronicles that after the death of his first wife Azubah, Caleb married Ephrath, and they had a son named Hur. (1 Chronicles2:19)
Hur, the firstborn of Ephrathah is father of Bethlehem. (1 Chronicles4:4)
This may probably be where we get the old name of Bethlehem which is Ephrathah.
Tracing the family tree further in the Toledot we have:
"Hezron became the father of Jerahmeel, Ram, and Caleb." (1 Chronicles 2:9)
According to St. Matthews’s genealogy of Jesus we read that Hezron has the sacred bloodline:
"Judah became the father of Perez and Zerah, whose mother was
Tamar. Perez became the father of Hezron, Hezron the father of Ram,"
Referring to Footnotes Ruth *[1:5] Boys: This word is used as a guide in the story line in that; when Ruth got married again and gave birth to a boy, her mother-in-law took care of him like her own son. With this Naomi now has a “boy” to replace her two lost “boys” (Footnotes Ruth * [4:16])
Footnotes Ruth * [1:11]
Other sons…husbands: the levirate
is a custom of the ancient Hebrews by which a man may be obliged to
marry his brother's widow which is stipulated in the Book of Deuteronomy “that his name may not be blotted out from Israel.”
We should also take note that there is no word in Hebrew for “cousin”. Probably
the word “brother” here applies to brothers and cousins as well as they all
call them “brothers”. Jesus has no brothers but his cousins are mentioned
as his “brothers” many times in the New Testament. (Matthew 12:46-47; Matthew 13:55; Matthew 17:1;
Mark 3:31; Mark 3:32; Mark 6:3; Luke 8:20-21; John 2:12; John 7:3; John 7:5; John 7:10).
Ruth [1:20] According Josephus’ Antiquities of the Jews Naomi also “signifies in the Hebrew tongue happiness, and Mara, sorrow.”
