Exodus 9:12

The fifth plague consisted of a severe Murrain, which carried off the cattle (מקנה, the living property) of the Egyptians, that were in the field. To show how Pharaoh was accumulating guilt by his obstinate resistance, in the announcement of this plague the expression, "If thou refuse to let them go" (cf. Exo 8:2), is followed by the words, "and wilt hold them (the Israelites) still" (עוד still further, even after Jehovah has so emphatically declared His will).

In this chapter we have an account of three more of the plagues of Egypt. I. Murrain among the cattle, which was fatal to them (Exo 9:1-7). II. Boils upon man and beast (Exo 9:8-12). III. Hail, with thunder and lightning. 1. Warning is given of this plague (Exo 9:13-21). 2. It is inflicted, to their great terror (Exo 9:22-26). 3. Pharaoh, in a fright, renews his treaty with Moses, but instantly breaks his word (Exo 9:27, etc.).

9:12 Plagues five and six apparently dissipated on their own, since there was no plea by Pharaoh to bring them to an end.
