Moses having an intimation from the Lord that one plague more would be
brought on Pharaoh, and then he would let Israel go, when they should
borrow of their neighbours jewels of gold and silver, the people being
in great favour with the Egyptians, \\#Ex 11:1-3\\, he declares to
Pharaoh, before he went out of his presence, the slaying of all the
firstborn in Egypt, which would issue in the dismission of Israel, and
then he went out from him in great anger, \\#Ex 11:4-8\\, but still
Pharaoh would not hearken, and his heart was hardened, and he refused
again to let Israel go, \\#Ex 10:9,10\\.
