Oh Allah! Islam reigned in Spain for 900 years, and "OhAllah" is now on the lips of all Castilian speaking Catholics in much the same way as Muslims would use it, "If God Wills It". Similarly, the Jews were in living within Kemet from 1847 - 1447 B.C. they would have been fully exposed to the worship of Amen. Like Oh Allah, Jews saw no point in creating new vocabulary when existing and familiar words could be recycled. Hence we have Amen today on the lips of all Jews, Christians and Muslims.
