The name Eshek (אֶשֶׁך) appears once in 1 Chronicles 8:39 as a descendant of Saul through the line of Azel. Eshek's sons were 'brave warriors and skilled archers' numbering 150 in all. His name may relate to the Hebrew root for 'oppression' or 'strength.'
The genealogy of Saul's descendants in 1 Chronicles 8–9 has profound theological resonance. After David became king, he honored his covenant with Jonathan by showing kindness to Mephibosheth (2 Samuel 9). The detailed preservation of Saul's extended genealogy demonstrates that God tracks and values every family line. The Benjaminite line continued to produce mighty warriors — foreshadowing the Apostle Paul, himself 'a Hebrew of Hebrews, from the tribe of Benjamin' (Philippians 3:5), who would become a mighty warrior for the Gospel.
