'As It is Written' in the Bible

so then, as it is written [in Scripture], “He who boasts and glories, let him boast and glory in the Lord.”

Do not be worshipers of handmade gods, as some of them were; just as it is written [in Scripture], “The people sat down to eat and drink [after sacrificing to the golden calf at Horeb], and stood up to play [indulging in immoral activities].”
