Three Officers on Every Chariot and the Hosts of Zerah the Cushite

Another interpretation of "and officers over all of them" (Exodus 14:7): three officers over each and every chariot. And some say thirty over each one. And some say three hundred over each and every one. But how did Pharaoh know how many of Israel had died during the three days of darkness? Rather, he brought out their census lists, and according to the census lists he raised up troops against them. Along the same lines Rabbi Yirmiyah expounded the verse, "And Zerah the Cushite went out against them with a host of a thousand thousand and three hundred chariots" (II Chronicles 14:8) - and according to the number of chariots he raised up troops against them. Another interpretation of "and officers over all of them": with the intent to destroy. In time past, "Every son that is born" (Exodus 1:22); but here, "and officers over all of them" with the intent to destroy, as it is said, "I will draw my sword" (Exodus 15:9).
