Not because we have not the right (ouc oti ouk ecomen exousian). Paul is sensitive on his right to receive adequate support ( 1 Thessalonians 2:6 ; 1 Corinthians 9:4 where he uses the same word exousian in the long defence of this right, 1 Corinthians 9:1-27 ). So he here puts in this limitation to avoid misapprehension. He did allow churches to help him where he would not be misunderstood ( 2 Corinthians 11:7-11 ; Php 4:45). Paul uses ouc oti elsewhere to avoid misunderstanding ( 2 Corinthians 1:24 ; 2 Corinthians 3:5 ; Philippians 4:17 ). But to make ourselves an ensample unto you (all ina eautou tupon dwmen umin). Literally, but that we might give ourselves a type to you. Purpose with ina and second aorist active subjunctive of didwmi. On tupon see on "1Th 1:7".
