Ramathaim-zophim may signify “the two hills 1Sa 9:11-13 of the watchmen,” so called from its being a post from which the watchmen looked out. But since Zuph is the name of the head of the family, it is more probable that Zophin means the Zuphites, the sons of Zuph (see Zophai, 1Ch 6:26), from whom the land about Ramah was called “the land of Zuph,” 1Sa 9:5.
There is reason to believe that Elkanah - an Ephrathite, or inhabitant of Bethlehem 1Sa 17:12; Rth 1:2 and of the territory of the tribe of Ephraim 1Ki 11:26 - the father of Samuel, represents the fifth generation of settlers in Canaan, and therefore that Samuel was born about 130 years after the entrance into Canaan - four complete generations, or 132 years - and about 40 years before David.
