1 Samuel 30:13

Then David asked him, “To whom do you belong, and where are you from?” “I am an Egyptian,” he replied, “the slave of an Amalekite. My master abandoned me three days ago when I fell ill.

And David said unto him, To whom belongest thou? and whence art thou? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days agone I fell sick.
