And ye know him not; but I know him; and if I said, I know him not, I should be like you, a liar. But I know him, and I keep his word.

Yet ye have not known him; but I know him: and if I should say, I know him not, I should be a liar like you: but I know him, and keep his saying.

and ye have not known Him, and I have known Him, and if I say that I have not known Him, I shall be like you, speaking falsely; but I have known Him, and His word I keep;

You do not know Him, but I know Him perfectly; and were I to deny my knowledge of Him, I should resemble you, and be a liar. On the contrary I do know Him, and I obey His commands.

You have no knowledge of him, but I have knowledge of him; and if I said I have no knowledge of him I would be talking falsely like you: but I have full knowledge of him, and I keep his word.

and yet you have not learned to know him; but I know him; and, if I were to say that I do not know him, I should be a liar like you; but I do know him, and I lay his message to heart.

(19) Yet ye have not known him; but I know him: and if I should say, I know him not, I shall be a liar like unto you: but I know him, and keep his saying.
(19) There is no right knowledge of God without Christ, neither is there any right knowledge of Christ without his word.

Yet ye have not known him,.... Not as the Father of Christ, nor as in Christ, whom to know is life eternal: they had no spiritual knowledge of him, nor communion with him; nor did they know truly his mind and will, nor how to worship and serve him as they ought:
but I know him; his nature and perfections, being of the same nature, and having the same perfections with him; and his whole mind and will lying in his bosom: nor did, or does any know the Father, but the Son, and he to whom he is pleased to reveal him:
and if I should say, I know him not, I should be a liar like unto you. Our Lord still intimates, that they were of their father the devil, and imitated him not only as a murderer, but as a liar: this is quite contrary to the character they give of themselves, for they say (x), that an Israelite will not tell a lie.
But I know him, and keep his saying: do his will, and always the things that please him, observe his law, preach his Gospel, fulfil all righteousness, and work out the salvation of men, which were the will and work of his Father he came to do.
(x) Maimon. in Misn. Pesachim, c. 8. sect. 6.

I shall be a liar like unto you--now rising to the summit of holy, naked severity, thereby to draw this long dialogue to a head.
