19 Therefore, when the Lord your God has given you rest from all your enemies in the land he is giving you as a special possession, you must destroy the Amalekites and erase their memory from under heaven. Never forget this!

Matthew Henry's Commentary on Deuteronomy 25:19

Commentary on Deuteronomy 25:17-19

(Read Deuteronomy 25:17-19)

Let every persecutor and injurer of God's people take warning from the case of the Amalekites. The longer it is before judgement comes, the more dreadful will it be at last. Amalek may remind us of the foes of our souls. May we be enabled to slay all our lusts, all the corruptions both within and without, all the powers of darkness and of the world, which oppose our way to the blessed Saviour.
