Exodus 13:4-5

On this day in early spring, in the month of Abib, you have been set free. You must celebrate this event in this month each year after the LORD brings you into the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites. (He swore to your ancestors that he would give you this land—a land flowing with milk and honey.)
