Firm, or a gift, a son of Obed, the son of Boaz and Ruth (Ruth 4:17, 22; Matt. 1:5, 6; Luke 3:32). He was the father of eight sons, the youngest of whom was David (1 Sam. 17:12). The phrase “stem of Jesse” is used for the family of David (Isa. 11:1), and “root of Jesse” for the Messiah (Isa. 11:10; Rev. 5:5). Jesse was a man apparently of wealth and position at Bethlehem (1 Sam. 17:17, 18, 20; Ps. 78:71). The last reference to him is of David’s procuring for him an asylum with the king of Moab (1 Sam. 22:3).
Jesse
Jesse is best known as David’s father. Ruth 4 closes with a quiet family line: Obed “is the father of Jesse, the father of David.” So Jesse’s grandmother was Ruth, the woman from Moab who stayed with Naomi. First Chronicles 2 lists his sons, with David “the seventh.” Scripture tells us little about Jesse himself in these verses; his place is in the line that leads to Israel’s greatest king. Begin with the book of Ruth to see how the story of his family starts.
