I speak that which I have seen with my Father: and ye do that which ye have seen with your father.

I speak the things which I have seen with my Father: and ye also do the things which ye heard from your father.

I, that which I have seen with my Father do speak, and ye, therefore, that which ye have seen with your father, ye do.'

The words I speak are those I have learnt in the presence of the Father. Therefore you also should do what you have heard from your father."

I say the things which I have seen in my Father's house: and you do the things which come to you from your father's house.

I say the things which I have seen with my Father; and you also do the things which you have heard from your father.'

I tell you what I have myself seen in the presence of my Father; and you, in the same way, do what you have learned from your father."

I speak what I have seen with my Father. He had already made frequent mention of his Father; and now, by an argument drawn from contrary things, he infers that they are enemies to God, and are the children of the devil, because they oppose his doctrine. "For my part," says he, "I bring nothing forward, but what I have learned from my Father. How comes it then that the word of God excites you to such fury, but because you have an opposite father?" He says that he speaks, and they do, because he discharged the office of a teacher, while they labored strenuously to extinguish his doctrine. At the same time, he protects the Gospel against contempt, by showing that it is not wonderful if it be opposed by the children of the devil Instead of you do, some render it, Do you what you have seen with your father; as if Christ had said, "Come, show that you are the children of the devil, by opposing me; for I speak nothing but what God has commanded."

I speak - John 3:11-13.
My Father - God.
Your father - The devil. See John 8:44. To see here means to learn of. They had learned of or been taught by the devil, and imitated him.

I speak that which I have seen - I speak nothing but that unchangeable, eternal truth which I have received from the bosom of God.
Ye do that which ye have seen - Instead of ἑωρακατε, ye have seen, I think we should read ηκουσατε, ye have heard, on the authority of BCKL, fifteen others; Coptic, Ethiopic, Armenian, later Syriac in the margin, Gothic, one copy of the Itala; Origen, Cyril, and Chrysostom. This reading, says Bishop Pearce, (who has adopted it), seems preferable to the other, because it could not be said, with the same propriety, that the Jews had seen any thing with their father the devil, as it could that Jesus had seen with his.
Jesus saw the Father, for he was the Word that was with God from eternity. The Jews did not see, they only felt and heard, their father the devil. It is the interest of Satan to keep himself out of sight, and to work in the dark.

I speak that which I have seen with my Father,.... This is an aggravation of the sin of the Jews, in seeking to kill Christ, on account of his doctrine, since it was not his own, but his Father's; was not merely human, but divine; was what he the only begotten Son, that lay in the bosom of his Father, had seen in his heart, in his purposes, and decrees, in his council, and covenant, and so was clear, complete, certain, and to be depended on:
and ye do that which ye have seen with your father; meaning the devil, whom, though they had not scan with their eyes, nor any of his personal actions; yet acted so much under his influence, and according to his will, as if they had close and intimate consultation with him, and took their plan of operation from him, and had him continually before them, as their example and pattern, to copy after. The Ethiopic version reads, "what ye have heard"; and so it is read in three of Beza's copies, and in three of Stephens's.

my Father . . . your father--(See on John 8:23).

I speak that which I have seen with my Father. Jesus was the Son; he had dwelt in the Father's house. They had the spirit of Satan, and hence were, spiritually, his children.
