In the eighth of God’s ten plagues against Egypt, He brings locusts, but this time, not just so that Pharaoh can know that Yahweh is God, but specifically so that the Israelites and their families will know that Yahweh is God. This emphasis on the family shows how God has bigger things in mind than just proving His power to a pagan Pharaoh, but showing His sovereignty to His promised people so that they may share it with their families forever.
