Exodus‬ ‭10‬:‭1-2

The Lord said to Moses, “Go to Pharaoh. I have made him and his officials stubborn. I did this so that I could show them my powerful miracles. I also did this so that you could tell your children and your grandchildren about the miracles and other wonderful things that I have done in Egypt. Then all of you will know that I am the Lord.” (‭Exodus‬ ‭10‬:‭1-2‬ ERV)
