He sent messengers to Abimelech at Arumah, saying, “Look, Gaal son of Ebed and his kinsfolk have come to Shechem, and they are stirring up the city against you.
When Gaal son of Ebed moved into Shechem with his kinsfolk, the lords of Shechem put confidence in him.
When Zebul the ruler of the city heard the words of Gaal son of Ebed, his anger was kindled.
Now therefore, go by night, you and the troops who are with you, and lie in wait in the fields.
