'On that Day' in the Bible

On that day they fasted there and said, "We have sinned against the LORD." Then Samuel judged the Israelis at Mizpah. When the Philistines heard that the Israelis had gathered at Mizpah, the Philistine lords came up against Israel. When the Israelis heard this, they were afraid of the Philistines.

Now it happened as Saul turned his back to leave Samuel, that God gave him another heart, and all these signs occurred on that day.

On that day the LORD delivered Israel, and the battle moved past Beth-aven.

The men of Israel were hard pressed on that day, and Saul required the army to take an oath: "Cursed is the person who eats food before evening and before I've been avenged of my enemies." So no one tasted food.

David told Abiathar, "I knew on that day when Doeg the Edomite was there that he would certainly tell Saul! I'm responsible for the deaths of your father's whole family.
