Genesis contains two significant prophecies about the name of the Israelite peoples. In the first, Genesis 21:12, God tells Abraham to send Ishmael and his mother away, "for in Isaac your seed shall be called." Paul repeats this twice in the New Testament (Romans 9:7; Hebrews 11:18). On the surface this seems to mean that God would consider Isaac's progeny to be the true sons of Abraham, and this is true. But it means so much more! It also means that Israel would call itself by the name "Isaac" in later times.
The second prophecy concerns Jacob's blessing on the sons of Joseph. In his prayer he asks God to "bless the lads; let my name be named upon them, and the name of my fathers Abraham and Isaac" (Genesis 48:16). This confirms God's words to Abraham, only this time it is specifically directed toward the birthright tribes of Ephraim and Manasseh. The descendants of Joseph would bear the names of the patriarchs, particularly Isaac.
Amos, written less than a half century before Israel fell, uses the name "Isaac" twice to refer to Israel:
The high places of Isaac shall be desolate, and the sanctuaries of Israel shall be laid waste. . . . Now therefore, hear the word of the LORD: You say, "Do not prophesy against Israel, and do not spout against the house of Isaac." (Amos 7:9, 16)
Israel may have already been calling itself "the house of Isaac" or "the sons of Isaac" even before their overthrow and captivity.
After Assyria fell, ancient records tell of a new people living around the shores of the Caspian Sea. These people were variously known as Sakai, Sacae, Sagetae, Sakki, Scyths, Scythians, Scuths, Scuits, Scolotoi, and Scots. In his book The Tribes, Yair Davidy writes:
SACCAE was the contemporary Middle Eastern term for Scyth and the name is believed to be a derivative of 'Isaac'. The appellation 'Saxe' or 'Saxon' is a further development of the same name. (p. 128)
Sharon Turner, author of History of the Anglo-Saxons, agrees, "Saka-Suna or the Sons of Sakai abbreviated into Saksun, which is the same sound as Saxon, seems a reasonable etymology of the word 'Saxon'" (p. 87). It takes no great leap of reason to conclude that "Saxons" is a corrupted form of "Isaac's sons."
Where do we find the Anglo-Saxon peoples living in these last days? In the very same place the Bible tells us Israel would be: northwestern Europe and its colonies!
