Renounceth not (ouk apotassetai). Old Greek word to set apart as in a military camp, then in the middle voice to separate oneself from, say good-bye to ( Luke 9:61 ), to renounce, forsake, as here. All that he hath (pasin toi eautou uparcousin). Dative case, says good-bye to all his property, "all his own belongings" (neuter plural participle used as substantive) as named in verse Luke 26 . This verse gives the principle in the two parables of the rash builder and of the rash king. The minor details do not matter. The spirit of self-sacrifice is the point.
