Gideon then pursued the two fugitive Midianite kings, Zebah and Zalmunna, on the other side of the Jordan, chastised those Israelites who refused him and his famishing warriors the needful provisions, and inflicted a crushing defeat upon the Midianites, from which they never recovered. The people thus delivered offered to make him their king, an honour which he declined, both for himself and his descendants. It appears that he made Ophrah a centre for pilgrims, to the detriment of the less conveniently situated sanctuary of Shiloh. This aroused the jealousy of the men of Ephraim, who, after the death of the hero, were involved in violent conflicts with the men of the tribe of Manasseh. Gideon had, after his great victories, carried the rich treasures of the vanquished enemies into the land. The towns of Israel became seats of wealth and luxury. Phœnician caravans could henceforth safely journey through the land. Covenants were concluded with the trafficking strangers, who were placed under the protection of the tutelar Baal-Berith (Baal of the Covenant). The jealous men of Ephraim, who sought to foment dissension among the seventy sons and grandsons of Gideon, found in Abimelech, one of his sons, an unscrupulous ally. This Abimelech, being the son of a woman of Shechem, was elected by the Shechemites to be their leader. His first act was to put his brothers to death. Only Jotham, the youngest of them, escaped. On Mount Gerizim, Jotham pronounced his trenchant parable of the trees, who, in their search of a ruler, met with refusals from the fruitful olive, fig, and vine trees. The prickly bramble (Atad) was the only one who would accept the government; but he warned the trees that if they refused to acknowledge him as ruler, he would send forth a fire to consume all the trees of the Lebanon. The parable found its application in the subsequent hostilities between the men of Shechem and Abimelech, whose cruelty ended in his death at the hand of his own armour-bearer. After the fall of Abimelech the cis-Jordanic tribes seem to have retrograded, while the men of Manasseh or Gilead, on the other side of the Jordan, invaded the high land of the Hauran, and took possession of sixty rock-built cities. This district then received the name Havvoth Jair. At that time the Israelites suffered a shock from two sides, which caused further disintegration among them. On the one hand they were attacked by the Ammonites, and on the other, by the Philistines. These attacks distracted them, and rendered them incapable of resistance. The Ammonites appear to have driven the Israelites from their open places, after which they attacked the strongholds. These incursions were successful against the tribes of Ephraim and Judah.
