and it shall be, that in the morning, as soon as the sun is up, you shall rise early, and rush on the city; and, behold, when he and the people who are with him come out against you, then may you do to them as you shall find occasion.
Gaal was evidently a Canaanite who disliked Abimelech (Judges 9:28) because he was the son of Gideon. He also opposed him because Gideon had both destroyed the altar of Baal in Ophrah and reestablished the worship of Yahweh in Israel (Judges 6:27; Judges 8:23). Gaal, whose name connects with a Hebrew word meaning "loathsome," and whose father’s name means "servant," did not want Abimelech to continue ruling over that part of Canaan. He did not want Shechem to remain under Abimelech’s control either.
