Now David was the son of that Ephrathite of Bethlehem Judah, whose name was Jesse; and he had eight sons: and the man was an old man in the days of Saul, stricken [in years] among men.
"David was the son of an Ephrathite of Bethlehem"  (1 Samuel 17:12). The correct translation of this was given by Keil, "David was the son of THAT Ephratite,"[11] thus referring to Jesse who was introduced in the preceding chapter.  This shows the continuity of the narrative and frustrates the false charges of "diverse sources."
