'It is Written' in the Bible

For it is written, "I will destroy the wisdom of the wise, and the intelligence of the intelligent I will confound."

so that, just as it is written, "The one who boasts, let him boast in the Lord."

But just as it is written, "[Things] which eye has not seen and ear has not heard, and have not entered into the heart of man, all that God has prepared for those who love him."

For the wisdom of this world is foolishness with God, for it is written, "The one who catches the wise in their craftiness,"

For in the law of Moses it is written, "You must not muzzle an ox [while it] is threshing." It is not about oxen God is concerned, is it?

Or doubtless does he speak {for our sake}? For it is written {for our sake}, because the one who plows ought to plow in hope and the one who threshes [ought to do so] in hope of a share.

and not become idolaters, as some of them [did], just as it is written, "The people sat down to eat and drink, and stood up to play,"

In the law it is written: "By those who speak a foreign language and by the lips of others I will speak to this people, and not even in this way will they obey me," says the Lord.

Thus also it is written, "The first man, Adam, became a living soul"; the last Adam [became] a life-giving spirit.
