After Sarah’s death Abraham married one of his concubines. Keturah already had six sons with Abraham, according to first Chronicles 1:32-34
Ishmael was there at Abraham’s death, and helped bury Abraham. Thus he had not moved far away yet.
Of particular interest is Ishmael’s second son, Kedar. His name is closely associated with Arabia. But Kedar lived much closer to Jerusalem than what the Muslims suggest. They claim he moved to what is now Mecca, but according to Isaiah 60:7 he must have lived much closer.
All Kedar’s flocks will be gathered to you,
the rams of Nebaioth will serve you;
they will be accepted as offerings on my altar,
and I will adorn my glorious temple.
The lambs and other animals used for sacrifices were raised much nearer Jerusalem so they could more easily be driven as herds.
And this is the reason God said: Esau have I hated. Esau did not consider the spiritual dimension of his birthright.
Verse 43 of the Obama impeachment song (as if sung by Obama to the tune of “Please release me, let me go”)
I’ll sign “Death to Israel”
although I am an infidel
12th Imam will rise from hell
with people who follow Ishmael.
