Deuteronomy 3:5

Then they turned and went up by the way of Bashan, and Og the king of Bashan went out to meet them, he and all his people for battle at Edrei.

“Then you came to this place, and Sihon the king of Heshbon and Og the king of Bashan came out to meet us for battle, but we struck them down;

and the golden mice, according to the number of all the cities of the Philistines belonging to the five lords, both of fortified cities and of country villages. The large stone on which they set the ark of Yahweh is a witness to this day in the field of Joshua the Beth-shemite.

“They captured fortified cities and a rich land. They took possession of houses full of every good thing, Hewn cisterns, vineyards, olive groves, Trees for food in abundance. So they ate, were filled, and grew fat, And reveled in Your great goodness.

Therefore the Jews of the rural areas, who live in the rural towns, make the fourteenth day of the month Adar a holiday for gladness and feasting and sending portions of food to one another.
