• Newari: “As many as were spared, escaped into Aphek city. Even there, the city wall collapsed and buried 27,000 bodies of them. Ben-hadad also went and escaped into the city and was hiding in the inner room of a house.” (Source: Newari Back Translation)
• Hiligaynon: “The remaining Arameanhon fled into the town of Afek, where the 27,000 of them were-fallen-upon by the stone-wall of the town. Ben Hadad also fled there, and hid in the most-inner room of the house.” (Source: Hiligaynon Back Translation)
