Cometh (erchetai). Futuristic present middle indicative of erchomai.
Yea, is come (kai elēluthen). Explanatory use of kai and the perfect active indicative as in Joh 12:23. The long-looked-for hour (hōra) is so close that it has virtually begun. The time for the arrest of Jesus is near. See also Joh 17:1.
That (hina). See Joh 16:2 for this same use of hina (not hote) with erchomai hōra.
Ye shall be scattered (skorpisthēte). First aorist passive subjunctive of skorpizō, used in Joh 10:12 of sheep scampering from the wolf. Cf. Mat 12:30; Luk 11:33.
To his own (eis ta idia). “To his own home” as in Joh 1:11; Joh 19:27. So Appian VI. 23.
Shall leave (aphēte). Second aorist subjunctive of aphiēmi with hina.
And yet (kai). Clear case of kai in adversative sense, not just “and.”
