NT.filter - rwp detachment:

rwp@Luke:9:61 @{And another also said} (\eipen de kai heteros\). A volunteer like the first. This third case is given by Luke alone, though the incident may also come from the same Logia as the other two. \Heteros\ does not here mean one of a "different" sort as is sometimes true of this pronoun, but merely another like \allos\ (Robertson, _Grammar_, p. 749). {But first} (\prton de\). He also had something that was to come "first." {To bid farewell to them that are at my house} (\apotaxasthai tois eis ton oikon mou\). In itself that was a good thing to do. This first aorist middle infinitive is from \apotass\, an old verb, to detach, to separate, to assign as a detachment of soldiers. In the N.T. it only appears in the middle voice with the meaning common in late writers to bid adieu, to separate oneself from others. It is used in strkjv@Acts:18:18| of Paul taking leave of the believers in Corinth. See also strkjv@Mark:6:46; strkjv@2Corinthians:2:13|. It is thus a formal function and this man meant to go home and set things in order there and then in due time to come and follow Jesus.

rwp@Matthew:16:18 @{And I also say unto thee} (\k'ag de soi leg\). "The emphasis is not on 'Thou art Peter' over against 'Thou art the Christ,' but on \Kag\: 'The Father hath revealed to thee one truth, and I also tell you another" (McNeile). Jesus calls Peter here by the name that he had said he would have (John:1:42|). Peter (\Petros\) is simply the Greek word for Cephas (Aramaic). Then it was prophecy, now it is fact. In verse 17| Jesus addresses him as "Simon Bar-Jonah," his full patronymic (Aramaic) name. But Jesus has a purpose now in using his nickname "Peter" which he had himself given him. Jesus makes a remarkable play on Peter's name, a pun in fact, that has caused volumes of controversy and endless theological strife. {On this rock} (\epi tauti ti petri\) Jesus says, a ledge or cliff of rock like that in strkjv@7:24| on which the wise man built his house. \Petros\ is usually a smaller detachment of the massive ledge. But too much must not be made of this point since Jesus probably spoke Aramaic to Peter which draws no such distinction (\Kph\). What did Jesus mean by this word-play?
