Ruth 2:1

Booz. The Scripture does not specify how nearly they were related. R. Josue says Elimelech, Salmon, and Tob (chap. iii. 13,) were brothers, and Booz was the son of Salmon, which cannot be refuted, (Serarius, q. 1.; Menochius) though the authority and proofs be very weak. It is not, however, more probable that Booz was the brother of Elimelech. Some think that he was not the immediate son of Salmon, as four persons seem too few to fill up the space of 366 years, from the marriage of Rahab till the birth of David. But this is not impossible. (Calmet) See chap. iv. 20.
