Hardly an absurdity BJ. Stick with me now and get your bible out :-)
Blot Out: 1. To make obscure, insignificant, inconsequential.
2. Wipe out, Destroy.
This verse taken literally and in context is very easy to understand. What is the "memory" of Amalek ? Quite simply him and his descendents. The Amalekites referred to here were the descendents of Amalek: son of Eliphaz: son of Esau and Adah (Gen.36:1-12).
Amalek lead his people into this aggresive(then came Amalek Ex.17:8), brutal, and cowardly(Dt.25:17-19) attack on Isreal. It was for this attack that God cut this people off.
This "blotting out" has been fulfilled, as there are no people on earth today known as or called the Amalekites. Ex.17:16 tells us how this was accomplished, done through war with all his generations. This war was carried on by Ehud (Judg.3:13-15): Barak (Judg.5:14): Gideon (Judg.6:3): Saul (1Sam.15): Samuel (1Sam.15:32-33): David (1Sam.27:8;30:1-17; 2Sam.8:12): and finally completed by the Simeonites in the time of Hezekiah (1Chr. 4:42-43).
These Amalekites were of course a branch of the Edomites(all being descendents of Esau-Edom, who of course was the brother of Jacob-Isreal). The history of the Edomites is one of many wars with Isreal, and quite unique in that the two nations started with Esau and Jacob, them being brothers. The Edomites were in fact a more advanced and stronger people(having Dukes and Kings Gen. 36) than the Isrealites at one point. Yet King David completely defeated them and made them subject to Isreal for approx. 150 years (2Sam.8:14), this of course being prophesied in Gen.25:23. In the Millenium, which is to come, the Edomites of that day will again be ruled by Isreal (Ps.60:8-10: Isa.11:14; 63:1; Amos 9:12).
This account in Ex.17:8-16 is one of an Idolatrous, warmongering people, who most likely attacked the Isrealites for their spoils, and did this while being fully aware that Isreal simply wanted passage through their land and posed no threat whatsoever. As stated in Dt. 25:17-19 they attacked in a cowardly manner and did this all even as miracles were being performed for Isreal right before their eyes, with no fear whatsoever of God. The Amalekites could not have been ignorant of God and his power, as they both were dwelling in the wilderness at that time and had probably watched Isreal for weeks prior to this. Quite pathetic indeed, and enough that God divinely through Moses and others wiped them off the face of the earth.
In this case "Memory" = Amalek and his descendents.
""So our mighty Lord has made sure that the memory of Amalek is in fact guaranteed to live forever, in God's inspired book!""
Indeed he has. That being to never forget that Rebellion, Idolatry, and a lack of fear of God, will at some point bring a provoked and invited sentence upon ones life unless there is spiritual change. "John 3:16"
Absurdity? No. Simple reminder ? Yes :-)
