The whole "final night" discourse in John is the referrent of tauta "these things" in15:11. Afterall, he moves immediately in 15:12 back into the mandatum first given in 13:34. Again in 16:25 we have tauta lelalEka and again in 17:1, tauta elalEsen. It is the whole program of mutual love, the Spirit Advocate, etc., which he is expounding. Keith Massey
