And the LORD said unto Moses, Write this for a memorial in a book, and rehearse it in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven.

And the Lord said to Moses: Write this for a memorial in a book, and deliver it to the ears of Josue: for I will destroy the memory of Amalec from under heaven.

And Jehovah said to Moses, Write this for a memorial in the book, and rehearse it in the ears of Joshua, that I will utterly blot out the remembrance of Amalek from under the heavens.

And Jehovah saith unto Moses, 'Write this, a memorial in a Book, and set it in the ears of Joshua, that I do utterly wipe away the remembrance of Amalek from under the heavens;'

And the Lord said to Moses, Make a record of this in a book, so that it may be kept in memory, and say it again in the ears of Joshua: that all memory of Amalek is to be completely uprooted from the earth.

The LORD said to Moses, 'Write this for a memorial on a scroll, and rehearse it in the ears of Joshua: that I will utterly blot out the memory of Amalek from under the sky.'

Then the Lord said to Moses: "Write this, as a memorial in a book, and deliver it to the ears of Joshua. For I will wipe away the memory of Amalek from under heaven."

Tunc dixit Jehova ad Mosen, Scribe illud pro memoriali in libro, et trade auribus Josuah: quoniam delendo delebo memoriam Amalec de sub coelo.

And the Lord said unto Moses. By this command God made it known that He had performed a work which not only ought to be celebrated by word of mouth, but which also was deserving of eternal glory with posterity; for therefore did He command it to be written in a book, that its memory might never perish. The dispute of commentators respecting this book seems to me to be superfluous; for God simply wills that the memorial of this circumstance should exist in all ages; and this was effected by the narration of Moses, for he handed down in writing even to the end of the world the praise of this favor, together with the perpetual and immortal doctrine of the Law. Yet God did not only wish the memorable event of this battle to be written down, but also that Joshua should be reminded of it, lest he should faint under the many difficulties which awaited him. For nothing could better support him with invincible firmness than the recollection of this history, from whence he might be assured that the people would ever be victorious under the auspices of God. But although this promise was not immediately fulfilled, yet the Amalekites were a long time afterwards totally destroyed by Saul; but it was a great encouragement to Joshua and the people to know that Amalek, who had first made war upon them, was already condemned by the divine decree, and could not escape the destruction to which he was devoted.

In a book - in the book, i. e. the book which contained the history of God's dealings with His people. Moses was further instructed to impress the command especially on the mind of Joshua, as the leader to whom the first step toward its accomplishment would be entrusted on the conquest of Canaan. The work was not actually completed until the reign of Hezekiah, 1-Chronicles 4:43.

Write this for a memorial in a book - This is the first mention of writing on record: what it signified, or how it was done, we cannot tell. But it is evident that either this passage is introduced here instead of Deuteronomy 25:17, by way of anticipation, or that by the words כתב שפר kethob and sepher was intended only a monumental declaration of the defeat of Amalek by Joshua, by some action or symbolical representation; for it is immediately subjoined, "And Moses built an altar, and called the name of it Jehovah-nissi." See Dr. A. Bayley, and see the note on Exodus 30 (note). It is very likely that the first regular alphabetical writing in the world was that written by the finger of God himself on the two tables of stone. What is said here was probably by way of anticipation, or means some other method of registering events than by alphabetical characters, if we allow that God gave the first specimen of regular writing on the tables of stone, which did not take place till some time after this.
Rehearse it in the ears of Joshua - Thus showing that Joshua was to succeed Moses, and that this charge should be given to every succeeding governor.
I will utterly put out the remembrance of Amalek - This threatening was accomplished by Saul, 1-Samuel 15:3, etc.; four hundred and twelve years after. Judgment is God's strange work; but it must take place when the sins which incensed it are neither repented of nor forsaken. This people, by their continued transgressions, proved themselves totally unworthy of a political existence; and therefore said God to Saul, Go, and utterly destroy the Sinners the Amalekites; 1-Samuel 15:18. So their continuance in sin was the cause of their final destruction.

And the LORD said unto Moses, Write this [for] a memorial (h) in a book, and rehearse [it] in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven.
(h) In the book of the law.

And the Lord said unto Moses,.... After the battle was over, and the Israelites had got the victory:
write this for a memorial in a book: not in loose papers, but in a book, that it might continue; meaning that the account of this battle with Amelek should be put down in the annals or journal of Moses, in the book of the law he was writing, or was about to write, and would write, as he did, see Joshua 1:7 that so it might be kept in memory, and transmitted to the latest posterity; it being on the one hand an instance of great impiety, inhumanity, and rashness, in Amalek, and on the other a display of the goodness, kindness, and power of God on the behalf of his people: and
rehearse it in the ears of Joshua; who was a principal person concerned in this battle, and therefore, when the account was written and rehearsed, could bear witness to the truth of it, as well as he was to be the chief person that should be concerned in introducing the Israelites into the land of Canaan, and subduing the Canaanites; and therefore this, and what follows, was to be rehearsed to him, as the rule of his conduct toward them, and particularly Amalek:
for I will utterly put out the remembrance of Amelek from under heaven; so that they shall be no more a nation, and their name never mentioned, unless with disgrace and contempt. This was fulfilled partly by Saul, 1-Samuel 15:8 and more completely by David, 1-Samuel 30:17, and the finishing stroke the Jews give to Mordecai and Esther, as the Targum of Jerusalem on Exodus 17:6.

Write this for a memorial--If the bloody character of this statute seems to be at variance with the mild and merciful character of God, the reasons are to be sought in the deep and implacable vengeance they meditated against Israel (Psalm 83:4).

As this battle and victory were of such significance, Moses was to write it for a memorial בּסּפר, in "the book" appointed for a record of the wonderful works of God, and "to put it into the ears of Joshua," i.e., to make known to him, and impress upon him, that Jehovah would utterly put out the remembrance of Amalek from under heaven; not "in order that he might carry out this decree of God on the conquest of Canaan, as Knobel supposes, but to strengthen his confidence in the help of the Lord against all the enemies of Israel. In Deuteronomy 25:19 the Israelites are commanded to exterminate Amalek, when God should have given them rest in the land of Canaan from all their enemies round about.
