Adam Clarke on John 7:34

Ye shall seek me, and shall not find me - When the Roman armies come against you, you will vainly seek for a deliverer. But ye shall be cut off in your sins, because ye did not believe in me; and where I am - in the kingdom of glory, ye cannot come; for nothing that is unholy shall enter into the new Jerusalem. In this, and the thirty-sixth verse, εἰμὶ, I am, is read by several εἷμι, I came, as in the twenty-ninth verse; and in these two last places the Ethiopic, Arabic, three copies of the Itala, Nonnus, and Theophylact, agree. See the note on Joh 7:29.
