Baana, son of Ahilud, had Taanach, Megiddo, and all of Beth Shean. (This was near Zarethan, below Jezreel, from Beth Shean to Abel Meholah and over to Jokmeam.)
The Lord threw the enemy into disorder in front of Israel and defeated them decisively at Gibeon. He chased them along the road that goes to the slope of Beth Horon and continued to defeat them all the way to Azekah and Makkedah.
As they fled from the Israelites down the slope of Beth Horon toward Azekah, the Lord threw huge hailstones on them. More died from the hailstones than from Israelite swords.
This is the territory for the families descended from Ephraim. The eastern border of the land they inherited is from Ataroth Addar to Upper Beth Horon.
