American Tract Society Bible Dictionary
The Hebrew word is used in two distinct significations.
1. Genesis 14:5; also some in the time of Moses. Og king of Bashan was of the Rephaim. In the time of Joshua, some of their descendants dwelt in the land of Canaan, Joshua 12:4 17:15 , and we hear of them in David's time, in the city of Gath, 1 Chronicles 20:4-6 . The giant Goliath and others were the remains of the Rephaim, or of the kindred family of Anakim. Their magnitude and strength are often spoken of in Scripture. They appear to have excelled in violence and crime, and hence are monuments of divine justice.
2. Job 26:5 ); Psalm 88:10; Proverbs 2:18; 21:16 , etc.
THE VALLEY OF THE REPHAIM, OR GIANTS, was famous in Joshua's time, Joshua 15:8 17:15 18:16 , and in the time of David, who here defeated the Philistines, 2 Samuel 5:18,22 1 Chronicles 11:6 14:9 . It was a broad and fertile valley, Isaiah 17:5 , beginning near the valley of Hinnom, and extending several miles south-west from Jerusalem, when it contracted to a narrow passage leading off towards the Mediterranean. It was in Judah, but near the border of Benjamin.
