Exodus 17:16

17:16 for he said, “For a hand was lifted up to the throne of the Lord ¹  – that the Lord will have war with Amalek from generation to generation.” ² 

Exodus 3:15

3:15 God also said to Moses, “You must say this to the Israelites, ‘The Lord ³  – the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob – has sent me to you. This is my name ⁴  forever, and this is my memorial from generation to generation.’ ⁵ 

[17:16]  ¹ tn The line here is very difficult. The Hebrew text has כִּי־יָד עַל־כֵּס יָהּ (ki yad ’al kes yah, “for a hand on the throne of Yah”). If the word is “throne” (and it is not usually spelled like this), then it would mean Moses’ hand was extended to the throne of God, showing either intercession or source of power. It could not be turned to mean that the hand of Yah was taking an oath to destroy the Amalekites. The LXX took the same letters, but apparently saw the last four (כסיה) as a verbal form; it reads “with a secret hand.” Most scholars have simply assumed that the text is wrong, and כֵּס should be emended to נֵס (nes) to fit the name, for this is the pattern of naming in the OT with popular etymologies – some motif of the name must be found in the sentiment. This would then read, “My hand on the banner of Yah.” It would be an expression signifying that the banner, the staff of God, should ever be ready at hand when the Israelites fight the Amalekites again.

[17:16]  ² sn The message of this short narrative, then, concerns the power of God to protect his people. The account includes the difficulty, the victory, and the commemoration. The victory must be retained in memory by the commemoration. So the expositional idea could focus on that: The people of God must recognize (both for engaging in warfare and for praise afterward) that victory comes only with the power of God. In the NT the issue is even more urgent, because the warfare is spiritual – believers do not wrestle against flesh and blood. So only God’s power will bring victory.

[3:15]  ³ sn Heb “Yahweh,” traditionally rendered “the Lord.” First the verb “I AM” was used (v. 14) in place of the name to indicate its meaning and to remind Moses of God’s promise to be with him (v. 12). Now in v. 15 the actual name is used for clear identification: “Yahweh…has sent me.” This is the name that the patriarchs invoked and proclaimed in the land of Canaan.

[3:15]  ⁴ sn The words “name” and “memorial” are at the heart of the two parallel clauses that form a poetic pair. The Hebrew word “remembrance” is a poetical synonym for “name” (cf. Job 18:17; Ps 135:13; Prov 10:7; Isa 26:8) and conveys the idea that the nature or character of the person is to be remembered and praised (S. R. Driver, Exodus, 24).

[3:15]  ⁵ tn The repetition of “generation” in this expression serves as a periphrasis for the superlative: “to the remotest generation” (GKC 432 §133.l).
