Albert Barnes Commentary 1 Samuel 9:1

"Now there was a man of Benjamin, whose name was Kish, the son of Abiel, the son of Zeror, the son of Becorath, the son of Aphiah, the son of a Benjamite, a mighty man of valor." — 1 Samuel 9:1 (ASV)

The genealogy of Saul is given here as far as Aphiah (called “Abiah” in 1 Chronicles 7:8), who was from the house of Becher, the son of Benjamin (Genesis 46:21). According to 1 Chronicles 9:35–39, Kish was the son of Ner, who was the son of Jehiel (also called Abiel here and in 1 Samuel 14:51). Jehiel was the first settler (or “father,” as stated in 1 Chronicles 9:35) at Gibeon, or Gibeah of Saul, and he married Maachah, a daughter or granddaughter of Caleb. If this is the case, it is obvious that the names of several generations are omitted between Kish and Abiel, including the one from which the family of Matri took its name (1 Samuel 10:21).
