[1:4] 1 tn John uses ζωή (zwh) 37 times: 17 times it occurs with αἰώνιος (aiwnios), and in the remaining occurrences outside the prologue it is clear from context that “eternal” life is meant. The two uses in 1:4, if they do not refer to “eternal” life, would be the only exceptions. (Also 1 John uses ζωή 13 times, always of “eternal” life.)
[1:4] sn An allusion to Ps 36:9, which gives significant OT background: “For with you is the fountain of life; In your light we see light.” In later Judaism, Bar 4:2 expresses a similar idea. Life, especially eternal life, will become one of the major themes of John’s Gospel.

[15:3] 3 sn The phrase you are clean already occurs elsewhere in the Gospel of John only at the washing of the disciples’ feet in 13:10, where Jesus had used it of the disciples being cleansed from sin. This further confirms the proposed understanding of John 15:2 and 15:6 since Judas was specifically excluded from this statement (but not all of you).
