I quote from the Holy Bible.
"Remember what Amalek did to you on the way when you went out of Egypt. That they encountered you on the way, and struck the hindmost, all that were weak at the
rear; and they did not fear G-d. Therefore it will be, when the Eternal, your G-d, gives you relief from all your enemies, all around, in the land that the Eternal, your G-d, is giving to you as an inheritance to possess it, then you shall wipe out the remembrance of Amalek
from beneath the heavens; you must not forget."
