The Targum Pseudo-Jonathan on Exodus 14:7 notices a strange detail in the chariot count. Pharaoh assembles six hundred choice chariots, plus all the chariots of his servants. But the Targumist asks: whose horses are pulling those chariots? After the plague of pestilence killed the Egyptian livestock (Exodus 9:3-6), and the plague of hail killed the rest, where did Egypt find horses for an army?
The Targum's answer is devastating. The chariots belong to "the Mizraee his servants, who were afraid of the Word of the Lord, lest they should be killed with pestilence, if not with hail." A minority of Egyptians, during the plagues, had feared God enough to shelter their livestock indoors. They listened to Moses' warnings (Exodus 9:20). They saved their animals.
And now Pharaoh drafts their animals to hunt the people whose God had saved them. The God-fearers of Egypt, the ones who almost got it right, supply the army that marches to the Sea of Reeds.
The Targum adds one more detail: "a third mule, for drawing and following swiftly, he added to each chariot." A reinforcement. Even a partial obedience to God earned survival during the plagues—and now that survival is being weaponized.
Takeaway: the Targum teaches that fearing God is only the first step; the ones who merely fear are still available to be conscripted by tyrants.
