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 GIANTS.)

[Giants]

ref'-a-im, re-fa'-im (repha'-im, from rapha', "a terrible one "hence "giant," in 1Ch 20:4, yelidhe ha-rapha', "sons of the giant"; the King James Version, Rephaims): A race of aboriginal or early inhabitants East of the Jordan in Ashterothkarnaim (Ge 14:5) and in the valley of Rephaim Southwest of Jerusalem (Jos 15:8). They associated with other giant races, as the Emim and Anakim (De 2:10,11) and the Zamzummim (De 2:20). It is probable that they were all of the same stock, being given different names by the different tribes who came in contact with them. The same Hebrew word is rendered "the dead," or "the shades" in various passages (Job 26:5 margin; Ps 88:10 margin; Pr 2:18 margin; Pr 9:18 margin; Pr 21:16 margin; Isa 14:9 margin; Isa 26:14,19 margin). In these instances the word is derived from rapheh, "weak," "powerless," "a shadow" or "shade."
