Ver. 19. Thou shalt blot out the remembrance of Amalek— Respecting the transaction here referred to, see Exodus 17 from the 8th verse to the end. This deletion of Amalek was completed by the death of Haman the Amalekite; Esther 3:1; Esther 7:10. See the Reflections on the Destruction of the Canaanites after chap. 20:
REFLECTIONS.—A dreadful memento is put upon Amalek. He had fallen upon them as soon as they had escaped from Egypt. He had taken advantage of their weakness, and attacked them when weary with marching, and faint with thirst. He had, in a cowardly manner hung upon their rear, to pick up the hindmost, who could make no resistance; and impiously feared not the Lord, whose glory appeared so visibly at their head. For these instances of treacherous cruelty to his people, God will punish him with utter excision; and they must not forget to execute the sentence, which was done at several times by Saul and David, and finally in the time of Hezekiah, 1 Chronicles 4:43. Note; (1.) God will avenge the quarrels of his people upon their enemies; and they will be especially remembered who seek to distress or discourage the weak, and to offend his little ones who are but beginning to escape from spiritual Egypt. (2.) God's sentence is slow in the execution, but it is sure.
