John 10:15 - Ellicott's Commentary On The Whole Bible

As the Father knoweth me, even so know I the Father. — Better,... and I know the Father. Our version, by its rendering, and by the division of verses, fails to give the full meaning, and there is thus, indeed, no reason for the assertion of the mutual knowledge of the Father and the Son. But connecting the words with those of the previous verse, we have, “I am the Good Shepherd, and know those who are Mine, and those who are Mine know Me, even as the Father knoweth Me, and I know the Father.” This deeper sense of union between the human spirit and Himself, and the wondrous likening of it to the union of Himself and the Father, is present to His mind as the close of His work on earth draws near. We find it again in John 14:20; John 15:10; John 17:8; John 17:21. It is bound up with the thought of the love which lays down His own life for them. This is repeated here and again in John 10:17-18.
