John 12:49-50

New King James Version

⁴⁹ For ^(A)I have not spoken on My own authority; but the Father who sent Me gave Me a command, ^(B)what I should say and what I should speak. ⁵⁰ And I know that His command is everlasting life. Therefore, whatever I speak, just as the Father has told Me, so I ^(C)speak.”
