Rephaim

Lofty men; giants, (Gen. 14:5; 2 Sam. 21:16, 18, marg. A.V., Rapha, marg. R.V., Raphah; Deut. 3:13, R.V.; A.V., "giants"). The aborigines of Palestine, afterwards conquered and dispossessed by the Canaanite tribes, are classed under this general title. They were known to the Moabites as Emim, i.e., "fearful", (Deut. 2:11), and to the Ammonites as Zamzummim. Some of them found refuge among the Philistines, and were still existing in the days of David. We know nothing of their origin. They were not necessarily connected with the "giants" (R.V., "Nephilim") of Gen. 6:4. (See [529]GIANTS.)

The Rephaim were the ancient giants of the land of Canaan. There were anciently several families of them in this country. It is commonly thought that they were descended from one called Rephah or Rapha;
