And Moses and Aaron did all these miraculous signs before Pharaoh. And Jehovah hardened the heart of Pharaoh, and he did not send away the sons of Israel from his land.
And Jehovah said to Moses, As you go to return to Egypt, see all the wonders which I have put in your hand, and do them before Pharaoh. And I will make strong his heart, and he will not send the people away.
O Jehovah, why do You make us wander from Your ways? You harden our heart from Your fear. For Your servants’ sake, return the tribes of Your inheritance.
“He has blinded their eyes” and “has hardened their heart,” “that they might not see with the eyes” and “understand with the heart,” “and turn back,” “and I should heal them.” Isa. 6:10
But if God, desiring to display wrath, and to make His power known, endured in much long-suffering vessels of wrath having been fitted out for destruction,
And Sihon the king of Heshbon was not willing to let us pass by him, for Jehovah your God had hardened his spirit, and had emboldened his heart, so as to give him into your hand, as it is this day.
For it was of Jehovah to harden their hearts, so that they should come against Israel in battle, so that they might be destroyed, so that they might have no favor, but that He might destroy them, as Jehovah commanded Moses.
And why do you make heavy your heart as the Egyptians and Pharaoh made heavy their heart? When He thrust hardly with them, did they not send them away? And they went.
