The story of Baasha actually begins with his immediate predecessor King Nadab, son of King Jeroboam (1 Kings 15:25). Baasha comes to power through a coup d’état, an assassination attempt on Nadab. Apparently Baasha has allies in the army with whom he conspires. Gibbethon is a city in Philistine territory, which was assigned to the tribe of Dan at the conquest of the land of Canaan. But the Danites lost this territory (Joshua 19:44, Joshua 19:47). In Joshua 21:23 it says that Gibbethon became a Levite city. In the time of King Baasha, Gibbethon was a Philistine city.
27 Baescha, fils d'Achija, de la maison d'Issacar, conspira contre lui, et Baescha le tua à Guibbethon, qui appartenait aux Philistins, pendant que Nadab et tout Israël assiégeaient Guibbethon.
