Bible writes of gaints,

Deut 2:10-11 "A race of giants called the Emites had once lived in the area of Ar. They were as strong and numerous and tall as the Anakites, another race of giants. Both the Emites and the Anakites are also known as the Rephaites, though the Moabites call them Emites."

Deut 2:20-21 "That area was once considered the land of the Rephaites, who had lived there, though the Ammonites call them Zamzummites. 21 They were also as strong and numerous and tall as the Anakites. But the Lord destroyed them so the Ammonites could occupy their land."
