Read To Hear: Exodusනියැදිය

Moses and Aaron performed all these wonders before Pharaoh, but the Lord hardened Pharaoh’s heart, and he would not let the Israelites go out of his country. (Exodus 11:10) 

REMEMBER that Pharaoh did not suddenly harden his heart, but he did it repeatedly up to seven times. The 7th time proved fatal for him!
