"the L–rd is a man of war': What is the intent of this? Because He revealed Himself at the sea as a hero waging war—"The L–rd is a man of war"—and He revealed Himself at Sinai as an elder full of mercy, viz. (Exodus 24:10) "And they saw the G–d of Israel … and under His feet as the work of a sapphire brick and as the appearance of the heavens in brightness" [[ see Rashi], and (Daniel 7:9) "I watched as thrones were set up, and the Ancient of Days sat … (10) A stream of fire was flowing forth from before Him, etc."—So as not to give a pretext to the peoples of the world to say that there are two (i.e., numerous) deities, (it is written) "The L–rd is a man of war—the L–rd is His name. It was He upon the sea, He in Egypt, He in the past, He in the future, He in time to come, He in this world, He in the world to come. As it is written (Devarim 32:39) "See, now, that it is I, I, and there is no god with Me, etc.", and (Isaiah 41:4) "Who wrought and did? The Caller of the generations (into being) from the beginning. I, the L–rd, was the first (to perform wonders and to help,) and it is I (who will be) with (you,) the later (generations."
