Judges 9:26-35

26And Gaal the son of Ebed came with his brethren, and went over to Shechem; and the men of Shechem put their trust in him. 27And they went out into the field, and gathered their vineyards, and trodthe grapes, and held festival, and went into the house of their god, and did eat and drink, and cursed Abimelech. 28And Gaal the son of Ebed said, Who is Abimelech, and who is Shechem, that we should serve him? is not he the son of Jerubbaal? and Zebul his officer? serve ye the men of Hamor the father of Shechem: but why should we serve him? 29And would that this people were under my hand! then would I remove Abimelech. And he said to Abimelech, Increase thine army, and come out.

30And when Zebul the ruler of the city heard the words of Gaal the son of Ebed, his anger was kindled. 31And he sent messengers unto Abimelech craftily, saying, Behold, Gaal the son of Ebed and his brethren are come to Shechem; and, behold, they constrain the city to take part against thee. 32Now therefore, up by night, thou and the people that are with thee, and lie in wait in the field: 33and it shall be, that in the morning, as soon as the sun is up, thou shalt rise early, and rush upon the city; and, behold, when he and the people that are with him come out against thee, then mayest thou do to them as thou shalt find occasion.

34And Abimelech rose up, and all the people that were with him, by night, and they laid wait against Shechem in four companies. 35And Gaal the son of Ebed went out, and stood in the entrance of the gate of the city: and Abimelech rose up, and the people that were with him, from the ambushment.
