2 Chronicles 9:24-25

24Every year, people who came to visit Solomon brought him gifts. They brought things that were made from silver and gold, as well as clothes, weapons, spices, horses and mules.

25Solomon had places to keep 4,000 horses that pulled his chariots. He also had 12,000 horses. He kept them in the cities that he had chosen for this and also in Jerusalem where he lived.
