Amalek

Amalek here functions as a symbol of predatory evil — the command to blot out his memory from under heaven represents God's ultimate verdict against those who prey on the weak.

Amalek is completely overwhelmed and defeated here — the victory attributed not to Joshua's military skill alone but to the sustained intercession supported by Aaron and Hur.

The Amalekites appear here as the recipients of Balaam's most blunt oracle — their early aggression against Israel after the Exodus earns them a prophesied end of 'utter destruction' with no redemptive future.
