Judges 20:23, 26

The sons of Israel went up and wept before the LORD until evening, and asked of the LORD, “Shall we advance again to battle against the sons of our brother Benjamin?” And the LORD said, “Go up against them.”

Then all the sons of Israel and all the people went up and came to Bethel and wept; and they sat there before the LORD and fasted that day until evening and offered burnt offerings and peace offerings before the LORD.
