JMNT(i)
28 Therefore Jesus cries out (or: spoke in a loud voice), as He is proceeding with teaching within the Temple grounds (court yards; porches), and continuing, says, “You have both seen and know Me, and you have seen and know where I am from (or: what is my source). And yet, I have not come from Myself (= on My own initiative or authority). On the contrary, the One sending Me is Real (True; Genuine), Whom you folks have not seen, neither know.
29 "I Myself have seen and know Him, because I am from His side (or: I continuously exist being at His side and in His presence) – and that One sent (or: that One also sends) Me forth as an Emissary with a mission (as a Representative)."
30 Then they began seeking to catch hold of and arrest (or: seize) Him – but still no one laid a hand upon Him, because His hour had not yet come.
