TSK · Exodus 7:14

and I have said to you, "Let my son go, that he may serve me;" and you have refused to let him go. Behold, I will kill your son, your firstborn.'"

The frogs shall depart from you, and from your houses, and from your servants, and from your people. They shall remain in the river only."

For if you refuse to let them go, and hold them still,

When Pharaoh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants.

Or else, if you refuse to let my people go, behold, tomorrow I will bring locusts into your country,

But Yahweh hardened Pharaoh's heart, and he wouldn't let them go.

Why then do you harden your hearts, as the Egyptians and Pharaoh hardened their hearts? When he had worked wonderfully among them, didn't they let the people go, and they departed?

Why then is this people of Jerusalem slidden back by a perpetual backsliding? they hold fast deceit, they refuse to return.

Yes, they made their hearts as hard as flint, lest they might hear the law, and the words which Yahweh of Armies had sent by his Spirit by the former prophets. Therefore great wrath came from Yahweh of Armies.
