Utterly destroy - Rather, "devote to destruction" (Leviticus 27:28 note). When a city or people were thus made cherem, everything living was to be destroyed, and no part of the spoil fall to the conquerors (compare 1 Samuel 15:21). The valuables were put into the sacred treasury.

Slay both man and woman - Nothing could justify such an exterminating decree but the absolute authority of God. This was given: all the reasons of it we do not know; but this we know well, The Judge of all the earth doth right. This war was not for plunder, for God commanded that all the property as well as all the people should be destroyed.

Now go and smite Amalek,.... This was one of the three things the Israelites were obliged to do when they came into the land of Canaan, as Kimchi observes; one was, to appoint a king over them, another, to build the house of the sanctuary, and the third, to blot out the name and memory of Amalek, see Deuteronomy 25:19 and this work was reserved for Saul, their first king:

and utterly destroy all that they have, and spare them not; all were to be devoted to destruction, and nothing remain to be made use of in any way, to any profit and advantage; living creatures were to be put to death, and everything else burnt and destroyed:

but slay both men and women, infant and suckling; neither sex nor age were to be regarded, no mercy and pity shown to any; they had shown none to Israel when weak and feeble, and by the law of retaliation none was to be exercised on them:

ox and sheep, camel and ass; though useful creatures, yet not to be spared; as not men, women, and children, through commiseration, so neither these through covetousness, and neither of them on any pretence whatsoever. Children suffered for their parents, and cattle because of their owners, and both were a punishment to their proprietors; an ox, or any other creature, might not be spared, lest it should be said, as Kimchi observes, this was the spoil of Amalek, and so the name and memory of Amalek would not be blotted out.

Saul is to smite and ban everything belonging to it without reserve, i.e., to put to death both man and beast. The last clause וגו is only an explanation and exemplification of וגו והחרמתּם. "From man to woman," etc., i.e., men and women, children and sucklings, etc.

Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but {b} slay both man and woman, infant and suckling, ox and sheep, camel and ass.

(b) That this might be an example of God's vengeance against those who deal cruelly with his people.

15:3 Destroy - Both persons and goods, kill all that live, and consume all things without life, for I will have no name nor remnant of that people left, whom long since I have devoted to utter destruction. Spare not - Shew no compassion or favour to any of them. The same thing repeated to prevent mistake, and oblige Saul to the exact performance hereof. Slay, and c. - Which was not unjust, because God is the supreme Lord of life, and can require his own when he pleaseth; infants likewise are born in sin, and therefore liable to God's wrath. Their death also was rather a mercy than a curse, as being the occasion of preventing their sin and punishment. Ox, and c. - Which being all made for man's benefit, it is not strange if they suffer with him, for the instruction of mankind.

15:1-9 The sentence of condemnation against the Amalekites had gone forth long before, Ex 17:14; De 25:19, but they had been spared till they filled up the measure of their sins. We are sure that the righteous Lord does no injustice to any. The remembering the kindness of the ancestors of the Kenites, in favour to them, at the time God was punishing the injuries done by the ancestors of the Amalekites, tended to clear the righteousness of God in this dispensation. It is dangerous to be found in the company of God's enemies, and it is our duty and interest to come out from among them, lest we share in their sins and plagues, Re 18:4. As the commandment had been express, and a test of Saul's obedience, his conduct evidently was the effect of a proud, rebellious spirit. He destroyed only the refuse, that was good for little. That which was now destroyed was sacrificed to the justice of God.
