Charles Ellicott Commentary Ruth 2:1

"And Naomi had a kinsman of her husband`s, a mighty man of wealth, of the family of Elimelech, and his name was Boaz." — Ruth 2:1 (ASV)

Boaz. —It has been already said that if there are any gaps in the genealogy, these are most probably to be referred to its earlier portion. According to the line, however, given in Ruth 4:18 and following, Boaz is grandson of the Nahshon who was prince of the tribe of Judah during the wanderings in the desert and son of Salmon and Rahab of Jericho. It may be noted that the difficulty of date may be lessened by supposing that in the last two generations we have children of their fathers’ old age.
