Old Testament

The Book of Exodus:
Chapter 10:21-24-27-29

Then the Lord said to Moses, "Stretch out your hand toward heaven, that there may be darkness over the land of Egypt, darkness which may even be felt." So Moses stretched out his hand toward heaven, and there was thick darkness in all the land of Egypt three days. They did not see one another; nor did anyone rise from his place for three days. But all the children of Israel had light in their dwellings.

Then Pharaoh called to Moses and said, "Go, serve the Lord; only let your flocks and your herds be kept back. Let your little ones also go with you."
But Moses said, "You must also give us sacrifices and burnt offerings, that we may sacrifice to the Lord our God. Our livestock also shall go with us; not a hoof shall be left behind. For we must take some of them to serve the Lord our God, and even we do not know with what we must serve the Lord until we arrive there."

But the Lord hardened Pharaoh's heart, and he would not let them go.
Then Pharaoh said to him, "Get away from me! Take heed to yourself and see my face no more! For in the day you see my face you shall die!" And Moses said, "You have spoken well. I will never see your face again."

New Testament

The Epistle of Paul the Apostle to the Romans:
Chapter 2:17-24-29

Indeed you are called a Jew, and rest on the law, and make your boast in God, and know His will, and approve the things that are excellent, being instructed out of the law, and are confident that you yourself are a guide to the blind, a light to those who are in darkness, an instructor of the foolish, a teacher of babes, having the form of knowledge and truth in the law. You, therefore, who teach another, do you not teach yourself? You who preach that a man should not steal, do you steal? You who say, "Do not commit adultery," do you commit adultery? You who abhor idols, do you rob temples? You who make your boast in the law, do you dishonor God through breaking the law?

For "the name of God is blasphemed among the Gentiles because of you," as it is written.
For circumcision is indeed profitable if you keep the law; but if you are a breaker of the law, your circumcision has become uncircumcision. Therefore, if an uncircumcised man keeps the righteous requirements of the law, will not his uncircumcision be counted as circumcision? And will not the physically uncircumcised, if he fulfills the law, judge you who, even with your written code and circumcision, are a transgressor of the law? For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God.
