Proverbs 9:18 But he knows not that the dead are there; and that her guests are in the depths of hell.
Rephaim is translated “giant” in Deuteronomy 2:11, 20; 3:11, 13; Joshua 12:4; 13:12; 15:8; 18:16; 2Samuel 21:16, 18, 20, 22; 1Chronicles 20:4, 6, 8. The phrase “remnant of the giants” in Deuteronomy 3:11 and Joshua 12:4; 13:12 should be “remnant of the Rephaims,” because there were many nations of giants other than the Rephaims who filled the whole country trying to contest God’s claim on the promised land. They are listed as Kenites, Kenizzites, Kadmonites, Hittites, Perizzites, Rephaims, Amorites, Canaanites, Girgashites, Jebusites, Hivites, Anakims, Emims, Horims, Avims, Zamzummims, Caphtorims, and Nephilims (Gen. 6:4; 14:5-6; 15:19-21; Ex. 3:8, 17; 23:23; Deut. 2:10-12, 20-23; 3:11-13; 7:1; 20:17; Jos. 12:4-8; 13:3; 15:8; 17:15; 18:16). Og was of the remnant of Rephaims, not the remnant of all other giant nations (Deut. 3:11; Jos. 12:4; 13:12).
All these giant nations came from a union of the sons of God (fallen angels) and daughters of men after the flood. Beings of great stature, some of them even had six fingers on each hand and six toes on each foot and carried spears weighing from 4,5 to 11 kilogrammes (2Sam. 21:16-22; 1Chr. 20:4-8). Goliath, whom David slew, wore a coat of armour weighing 89 kilogrammes and was 3 metres tall (1Sam. 17:4-6). The pyramids of Egypt, the giant cities of Bashan and other huge monuments of construction may remain a mystery until they are accepted as the result of the labour and skill of giants.
The revelation of giants in Scripture gives us a true picture of what Greek mythology tries vainly to give. Mythology is but the outgrowth of traditions, memories, and legends telling of the acts of supernatural fathers and their giant offspring – the perversion and corruption in the transmission of actual facts concerning these mighty beings. The fact that giants were partly of supernatural origin made it easy for humans to regard them as gods.
