Comentario citado sobre Jeremías 46:9

TZALALU’ AS LEAD. They went down into “the depths” (m’tzoloth) of the sea as lead. Now Moses mentioned this in the Song twice: They went down into the sea like a stone,¹⁷³Verse 5. and as lead, [mentioned in the verse here], in order to emphasize that this too came upon them from the hand of G-d. There were many persons among the Egyptians who knew how to swim, and they were near dry land, and surely all those who rode on the horses could be expected to be saved since horses are accustomed to swimming in water. Similarly, those that handle the shield¹⁷⁴Jeremiah 46:9. The shield can serve as a board for passing through the surf. See Yebamoth 121 a where Rabbi Akiba relates that once when his boat drowned “I chanced upon a board of the boat and every wave that came upon me I bent my head” and he was thus saved. can save themselves in water, and here not one of them escaped! This is the meaning of the verse, And the Eternal overthrew (‘vay’na’er’) the Egyptians in the midst of the sea.¹⁷¹Above, 14:27. He lifted them with His rough blast,¹⁷⁵Isaiah 27:8. and He lowered them into the sea. The usage of the word is similar to that in the verses: And the wicked ‘v’yina’aru’ (shall be shaken) out of it;¹⁷⁶Job 38:13. And the strong shall be ‘lin’oreth’ (as tow),¹⁷⁷Isaiah 1:31. ‘n’oreth’ being that which is separated and falls off from the flax when it is being prepared [for spinning].
