Exodus 9:13-29

6. The seventh, eighth, and ninth plagues 9:13-10:29

Moses announced the purpose of the following plagues to Pharaoh "in the morning" (cf. Exodus 7:15; Exodus 8:20). This purpose was twofold: that Pharaoh personally might know God’s power (Exodus 9:14) and that the whole world might know it (Exodus 9:16; cf. Romans 9:17).
