Matthew 5:16-18

Young's Literal Translation

¹⁶ so let your light shine before men, that they may see your good works, and may glorify your Father who [is] in the heavens.

¹⁷ `Do not suppose that I came to throw down the law or the prophets -- I did not come to throw down, but to fulfill;

¹⁸ for, verily I say to you, till that the heaven and the earth may pass away, one iota or one tittle may not pass away from the law, till that all may come to pass.
