John 15:17

17. ταῦτα. The verse sums up what precedes and prepares for a new departure (comp. John 15:11; John 14:25; John 16:1; John 16:25; John 16:33), ταῦτα referring to what has been said about being one with Him and with one another. For ἵνα see on John 1:8 and comp. John 15:12; John 11:57; John 13:34. The idea of purpose is probably to be included.

Note the solemn effect produced by prolonged asyndeton. In John 15:1-17 there is not a single connective particle. A Greek uninfluenced by Hebrew would be very unlikely to write thus. see on John 1:6.
