NET
30 I can do nothing on my own initiative. Just as I hear, I judge, and my judgment is just, because I do not seek my own will, but the will of the one who sent me.
Darby
30 I cannot do anything of myself; as I hear, I judge, and my judgment is righteous, because I do not seek my will, but the will of him that has sent me.
KJV
30 “I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.”
