It was not after the spirit or mission of the Law to aim at overcoming inveterate opposition by love and by attempts at conversion (contrast Luke 9:55-56). The law taught God's hatred of sin and of rebellion against Him by enjoining the extinction of the obstinate sinner. The Amalekites were a kindred people Genesis 36:15-16; and living as they did in the peninsula of Sinai, they could not but have well known the mighty acts God had done for His people in Egypt and the Red Sea; yet they manifested from the first a persistent hostility to Israel (compare Exodus 17:8, and note; Numbers 14:45). They provoked therefore the sentence here pronounced, which was executed at last by Saul (1 Samuel 15:3 ff).

Remember what Amalek did unto thee,.... The Amalekites, how they came out against them, and fought with them at Rephidim, Exodus 17:8,

by the way, when ye were come forth out of Egypt; which was an aggravation of their cruel and inhuman action, that they not only came out against them unprovoked, were the aggressors, and fell upon them as they were travelling on the road, but when they were just come out of Egypt, where they had been in hard bondage, and their spirits broken, and they not used to war; and so took them at all these disadvantages, a people that had not in the least injured them.

But whilst the Israelites were to make love the guiding principle of their conduct in their dealings with a neighbour, and even with strangers and foes, this love was not to degenerate into weakness or indifference towards open ungodliness. To impress this truth upon the people, Moses concludes the discourse on the law by reminding them of the crafty enmity manifested towards them by Amalek on their march out of Egypt, and with the command to root out the Amalekites (cf. Exodus 17:9-16). This heathen nation had come against Israel on its journey, viz., at Rephidim in Horeb, and had attacked its rear: "All the enfeebled behind thee, whilst thou wast faint and weary, without fearing God." זנּב, lit., to tail, hence to attack or destroy the rear of an army or of a travelling people (cf. Joshua 10:19). For this reason, when the Lord should have given Israel rest in the land of its inheritance, it was to root out the remembrance of Amalek under heaven. (On the execution of this command, see 1 Samuel 15.) "Thou shalt not forget it:" an emphatic enforcement of the "remember" in Deuteronomy 25:17.

Remember what Amalek did unto thee by the way, when ye were come forth out of Egypt;

25:17 Out of Egypt - Which circumstance greatly aggravates their sin, that they should do thus to a people, who had been long exercised with sore afflictions, to whom pity was due by the laws of nature and humanity, and for whose rescue God had in so glorious a manner appeared, which they could not be ignorant of. So this was barbarousness to Israel, and setting the great Jehovah at defiance.

17-19. Remember what Amalek did-This cold-blooded and dastardly atrocity is not narrated in the previous history (Ex 17:14). It was an unprovoked outrage on the laws of nature and humanity, as well as a daring defiance of that God who had so signally shown His favor towards Israel (see on [162]1 Samuel 15; [163]27. 8; [164]30).

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.
