A.T. Robertson Commentary John 8:16

"Yea and if I judge, my judgment is true; for I am not alone, but I and the Father that sent me." — John 8:16 (ASV)

Yea and if I judge (κα εαν κρινω δε εγω). "And even if I pass judgment." Condition of third class again.

True (al thin). See 1:9 for αληθινος, genuine, soundly based (cf. δικαια in 5:30), "satisfying our perfect conception" (Westcott), not merely true (αληθες) in the particular facts (verse 14).

For I am not alone (οτ μονος ουκ ειμ). Jesus now takes up the technical criticism in verse 13 after justifying his right to speak concerning himself.

But I and the Father that sent me (αλλ εγω κα ο πεμψας με πατηρ). See 16:32 for a like statement about the Father being with Christ. It is not certain that πατηρ is genuine here (omitted by Aleph D, but in B L W), but the Father is clearly meant as in 7:18,33. Jesus gives the Father as the second witness.
