{My time is not yet come} (ho kairos ho emos oup(930a)parestin). Only use with verse  8  of kairos in this Gospel,
elsewhere chronos ( Joh 5:6 ) or more often h(9372)a ( 2:4 ) "the
predestined hour" (Bernard). Here kairos is the fitting or
proper occasion for Christ's manifesting himself publicly to the
authorities as Messiah as in verse  8 . At the feast of
tabernacles Jesus did make such public claims ( 7:29,33  8:12,28,38,42,58 ). Parestin is present active indicative of
pareimi, old compound, to be by, to be present. The brothers of
Jesus had the regular Jewish obligation to go up to the feast,
but the precise day was a matter of indifference to them.
