🔼The name Kiriath-sepher in the Bible
Kiriath-sepher was the original name of a city later called Debir (Joshua 15:15), and apparently it was also known as Kiriath-sannah (Joshua 15:49). When the boundaries of the land of Judah were established, Caleb son of Jephunneh received his own territory, and Debir (or Kiriath-sepher) was in it.
Caleb proclaimed that whoever would capture Kiriath-sepher would receive his daughter Achsah for a wife. Caleb's nephew Othniel, son of Kenaz, rose up to the challenge, captured the city and became Caleb's son in law (Joshua 15:17, Judges 1:12). While Othniel had his mind set on warring and bedding, Achsah opted for settling down, and asked her father Caleb for a field with springs, which she promptly received (Joshua 15:19, Judges 1:15).
It's probably no coincidence that the author of the story depicts the man who conquers the "city of learning" as one who retires from combat and begins to listen to his wife. Othniel became Israel's first judge. He successfully battled the oppressing king Cushan-rishathaim of Aram-naharaim and governed the land for forty peaceful years (Judges 3:9).
