The prince of this world (ὁ ἄρχων ροῦ κόσμου τούτου)
The phrase occurs only in the Gospel; here, Joh 14:30; Joh 16:11.
Shall be cast out (ἐκβληθήσεται ἔξω)
In every case but one where the word ἐκβάλλω occurs in John, it is used of casting out from a holy place or society. See Joh 2:15; Joh 9:34, Joh 9:3; 3Jo 1:10; Rev 12:2. Compare Joh 10:4.
