Acts 7:51

Circumcise therefore the foreskin of your heart, and be no more stiffnecked.

And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.

And that I also have walked contrary unto them, and have brought them into the land of their enemies; if then their uncircumcised hearts be humbled, and they then accept of the punishment of their iniquity:

But they rebelled, and vexed his holy Spirit: therefore he was turned to be their enemy, and he fought against them.

Circumcise yourselves to the LORD, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem: lest my fury come forth like fire, and burn that none can quench it, because of the evil of your doings.

For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.

For the LORD had said unto Moses, Say unto the children of Israel, Ye are a stiffnecked people: I will come up into the midst of thee in a moment, and consume thee: therefore now put off thy ornaments from thee, that I may know what to do unto thee.

And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:

Unto a land flowing with milk and honey: for I will not go up in the midst of thee; for thou art a stiffnecked people: lest I consume thee in the way.

And they were not able to resist the wisdom and the spirit by which he spake.

In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:

For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.

To whom our fathers would not obey, but thrust him from them, and in their hearts turned back again into Egypt,

And might not be as their fathers, a stubborn and rebellious generation; a generation that set not their heart aright, and whose spirit was not stedfast with God.

And he said, If now I have found grace in thy sight, O LORD, let my LORD, I pray thee, go among us; for it is a stiffnecked people; and pardon our iniquity and our sin, and take us for thine inheritance.

Thus saith the Lord GOD; No stranger, uncircumcised in heart, nor uncircumcised in flesh, shall enter into my sanctuary, of any stranger that is among the children of Israel.

But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction.

For they are impudent children and stiffhearted. I do send thee unto them; and thou shalt say unto them, Thus saith the Lord GOD.

But they and our fathers dealt proudly, and hardened their necks, and hearkened not to thy commandments,
