New Defender's Study Bible Notes
14:5 Rephaims. Some of these Canaanite tribes seem actually to have been demon-possessed, in the same manner as the demon-energized population before the Flood (see notes on Genesis 6:1-4). The Rephaim (“strong ones”) and the Zamzummim (“powerful ones,” probably the same as the Zuzim) along with the Emim, all seem to have been of “the sons of Anak” or the Anakim, and all seem to have been giants (note Deuteronomy 2:10,20; Joshua 15:13). In Numbers 13:33, these Anakim are actually said to have been “giants” (Hebrew nephilim, the same word as used in Genesis 6:4). Furthermore, the term rephaim is also used to refer to some of the spirits of the wicked dead in Hades (Job 26:5; Proverbs 2:18; 9:18; 21:16; Isaiah 14:9; 26:14). All of this suggests another irruption of demonic spirits after the Flood, possibly at the rebellion at Babel, with giant progeny again being produced through demon-possessed parents. Their descendants inhabited Canaan.
