'Rephaites' in the Bible

The territory of King Og of Bashan, one of the few remaining Rephaites, who lived in Ashtaroth and Edrei

the whole kingdom of Og in Bashan, who ruled in Ashtaroth and Edrei. (He was one of the few remaining Rephaites.) Moses defeated them and took their lands.

It then went up the Valley of Ben Hinnom to the slope of the Jebusites on the south (that is, Jerusalem), going up to the top of the hill opposite the Valley of Ben Hinnom to the west, which is at the end of the Valley of the Rephaites to the north.

Joshua replied to them, "Since you have so many people, go up into the forest and clear out a place to live in the land of the Perizzites and Rephaites, for the hill country of Ephraim is too small for you."

The border then descended to the edge of the hill country near the Valley of Ben Hinnom located in the Valley of the Rephaites to the north. It descended through the Valley of Hinnom to the slope of the Jebusites to the south and then down to En Rogel.
