Matthew 5:46-48

Revised Standard Version

⁴⁶ For if you love those who love you, what reward have you? Do not even the tax collectors do the same? ⁴⁷ And if you salute only your brethren, what more are you doing than others? Do not even the Gentiles do the same? ⁴⁸ You, therefore, must be perfect, as your heavenly Father is perfect.
