The Biblical patriarch Abraham had two sons, and the first was Ishmael.

Of Ishmael, the father of the Arab nations, The Sword of the Lord has this to say:

And the angel of the LORD said unto her, I will multiply thy seed exceedingly, that it shall not be numbered for multitude.
And the angel of the LORD said unto her, Behold, thou art with child and shalt bear a son, and shalt call his name Ish'mael; because the LORD hath heard thy affliction.
And he will be a wild man; his hand will be against every man, and every man's hand against him; and he shall dwell in the presence of all his brethren. Genesis 16:10-12

The Word of God has more to say about Ishmael:

And as for Ish'mael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. Genesis 17:20

The Lord Jehovah God guarantees us that the Arab-Muslim world will be a force to be reckoned with until The Last Day.

I would gladly lay aside the use of arms and settle matters by negotiation, but unless the whole will, the matter ends, and I take up my battle rifle, and thank God that He has put it within my grasp.
