Hawker's Poor Man's Concordance And Dictionary [1]

This man was the husband of Naomi, whom we read of with such honourable testimony for her faith in God, in the book of Ruth; and as so much is contained in that sweet fragment of sacred Scripture, in allusion to the Lord Jesus Christ, I thought it proper to notice in this place, this name. The whole of the book of Ruth is interesting, not only as a true history of events which took place in the church, but, like that of Joseph, is typical and figurative of higher things. The certain man, there spoken of, going down from Bethlehem-judah, the land of bread, to sojourn in Moab, the city of destruction, becomes no unapt representation of our first father, who, like the Samaritan our Lord describes, going down from Jerusalem, the holy city, to Jericho, the cursed city, fell among thieves. ( Luke 10:30) And as the persons of this certain man and his family were types of others, so their names were significant also of their history. Elimelech means, my God, a king; Naomi signifies, a pleasant one; and their sons, Mahlon and Chilion, sickness and consumption; for such will always be the fruits of leaving Jesus for the world. (See  Ruth 1:1 -  Ruth 4:22 throughout.)

Hastings' Dictionary of the Bible [2]

ē̇ - lim´e - lek ( אלימלך , 'ĕlı̄melekh , "my God is king"; Ἀβειμέλεχ , Abeimélech , Ἀλιμέλεκ , Alimélek ): Elimelech was a member of the tribe of Judah, a native of Bethlehem Judah, a man of wealth and probably head of a family or clan (Rth 1:2, Rth 1:3; Rth 2:1, Rth 2:3). He lived during the period of the Judges, had a hereditary possession near Bethlehem, and is chiefly known as the husband of Naomi, the mother-in-law of Ruth and ancestress of David the king. Because of a severe famine in Judea, he emigrated to the land of Moab with his wife and his sons, Mahlon and Chilion. Not long afterward he died, and his two sons married Moabite women, Ruth and Orpah. Ten years in all were spent in Moab, when the two sons died, and the three widows were left. Soon afterward Naomi decided to return to Judah, and the sequel is told in the Book of Ruth. See Ruth; Naomi .
