Judges 20:23, 26

And the people of Israel went up and wept before the LORD until the evening. And they inquired of the LORD, “Shall we again draw near to fight against our brothers, the people of Benjamin?” And the LORD said, “Go up against them.”

Then all the people of Israel, the whole army, went up and came to Bethel and wept. They sat there before the LORD and fasted that day until evening, and offered burnt offerings and peace offerings before the LORD.
