Matthew 7:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ You will know them by their fruits. Are grapes gathered from thorns, or figs from thistles? ¹⁷ In the same way, every good tree bears good fruit, but the bad tree bears bad fruit. ¹⁸ A good tree cannot bear bad fruit, nor can a bad tree bear good fruit.
