Judges 9:30

27 And they went out into the fields, and gathered their vineyards, and trode [the grapes], and made merry, and went into the house of their god, and did eat and drink, and cursed Abimelech.

28 And 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 the men of Hamor the father of Shechem: for why should we serve him?

29 And would to God this people were under my hand! then would I remove Abimelech. And he said to Abimelech, Increase thine army, and come out.

30 And when Zebul the ruler of the city heard the words of Gaal the son of Ebed, his anger was kindled.

31 And he sent messengers unto Abimelech privily, saying, Behold, Gaal the son of Ebed and his brethren be come to Shechem; and, behold, they fortify the city against thee.

32 Now therefore up by night, thou and the people that [is] with thee, and lie in wait in the field:

33 And it shall be, [that] in the morning, as soon as the sun is up, thou shalt rise early, and set upon the city: and, behold, [when] he and the people that [is] with him come out against thee, then mayest thou do to them as thou shalt find occasion.
