You teach us an error alien to His will, draw us away from the path according to the Mosaic Law, and transfer us to something pleasing only to You." Such things the Jews probably whispered in secret or pondered within themselves.
The Lord again forestalls them, knowing the movements of thought occurring in them, for He is true God. Therefore He says: "I speak what I have seen with the Father." I have beheld the nature of My Father. Of Myself and in Myself I have seen the Begetter and have become the beholder of His desires. Clearly, I have seen by innate knowledge what deeds He loves, and this I "speak" to you.
I do not appear at all to speak contrary to Him, nor have I established anything against His will. I strive to call My hearers to this, without departing from My own desires. For His desires are in Me, and Mine likewise are in Him. But if I, being such by nature and being of one will in all things with God the Father, seem to you untrue and am considered to be turning you away from the divine instructions, let such an accusation cease. Cast away such suspicion.
"What you have heard from the Father, do." He spoke to you through Moses. Fulfill the commandment. You heard His words: "You shall not kill the innocent and righteous" (Ex 23:7). How then do you seek to kill Me, thereby violating the Father's commandment?
But the saying can also be understood in another sense: "And you also, therefore, do what you have heard from the Father." He spoke to you through the prophets. You heard the words: "Rejoice greatly, O daughter of Zion! Proclaim, O daughter of Jerusalem! Behold, your King comes to you, righteous and saving, mounted on a young colt, the foal of a beast of burden" (Zech 9:9).
Again also by the voice of Isaiah: "Go up on a high mountain, you who bring good tidings to Zion! Lift up your voice with strength, you who bring good tidings to Jerusalem! Lift it up, fear not! Behold your God. Behold, the Lord comes with strength, and His arm with authority. Behold, His reward is with Him and His work before Him. He will feed His flock like a shepherd, and with His arm He will gather the lambs and comfort those with young" (Is 40:9-11).
Therefore, obeying the Father's commandments, receive Him who was proclaimed beforehand. Honor with faith the One announced beforehand. At least give the Father's words authority within yourselves.
One must know that when He says the Law belongs to God the Father, although it was uttered by Him through angels, He does not exclude Himself from the giving of the Law. Rather, He does this in condescension to the Jews, who thought this was how it had been, and for their profit He does not refute their opinion. For He often shamed them for not receiving Him by bringing forward the Father's name.
