'It is Written' in the Bible

so that the promise should be made sure to all Abraham's true descendants; not merely to those who are righteous through the Law, but to those who are righteous through a faith like that of Abraham. Thus in the sight of God in whom he believed, who gives life to the dead and makes reference to things that do not exist, as though they did, Abraham is the forefather of all of us. As it is written, "I have appointed you to be the forefather of many nations."

And how are men to preach unless they have been sent to do so? As it is written, "How beautiful are the feet of those who bring glad tidings of good!"

Do not be revengeful, my dear friends, but give way before anger; for it is written, "'Revenge belongs to Me: I will pay back,' says the Lord."

for it is written, "'As I live,' says the Lord, 'to Me every knee shall bow, and every tongue shall make confession to God.'"

and that the Gentiles also have glorified God in acknowledgment of His mercy. So it is written, "For this reason I will praise Thee among the Gentiles, and sing psalms in honour of Thy name."
