When we speak of giants in the Bible and the Nephilim, we can’t forget to consider the Rephaim (Genesis 14:5).
One of the definitions of Rephaim, according to the Jews, are a people group of greater-than-average height and stature (Deuteronomy 2:20-21) also known as the Zamzummim. They were as tall as the Anakim, according to Scripture, which are other giants in the land.
Where did these giants come from? Some would argue that they can be traced back to Genesis 6.
