Deuteronomy 25:17

Verse 17. Amalec. This order for destroying the Amalecites, in the mystical sense, sheweth how hateful they are to God, and what punishments they are to look for from his justice, who attack and discourage his servants when they are but just come out, as it were, of the Egypt of this wicked world, and being yet weak and faint-hearted, are but beginning their journey to the land of promise.
