Judges 9:31 KJV

29And 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.

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 privily, saying, Behold, Gaal the son of Ebed and his brethren be come to Shechem; and, behold, they fortify the city against thee.

32Now therefore up by night, thou and the people that is 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 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.
