Matthew 24:23-25

Young's Literal Translation

²³ `Then if any one may say to you, Lo, here [is] the Christ! or here! ye may not believe;

²⁴ for there shall arise false Christs, and false prophets, and they shall give great signs and wonders, so as to lead astray, if possible, also the chosen.

²⁵ Lo, I did tell you beforehand.
