Exodus 9:2

For if thou shalt refuse to let them go, and wilt hold them still,

And if thou shalt refuse to let them go, behold, I will smite all thy borders with frogs:

And I say to thee, Let my son go, that he may serve me: and if thou shalt refuse to let him go, behold, I will slay thy son, even thy first-born.

But if ye will not hearken to me, and will not do all these commandments;

And if ye will not be reformed by me by these things, but will walk contrary to me;

And if ye will not for all this hearken to me, but walk contrary to me;

God judgeth the righteous, and God is angry with the wicked every day.

But God will wound the head of his enemies, and the hairy scalp of such one as goeth on still in his trespasses.

But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.

But to them that are contentious, and do not obey the truth, but obey unrighteousness; indignation and wrath:

And I gave her time to repent of her lewdness, and she repented not.

And men were scorched with great heat, and blasphemed the name of God, who hath power over these plagues: and they repented not to give him glory.
