John 13:29
Nestle 1904 Greek New Testament · Berean Standard Bible
τινὲς γὰρ ἐδόκουν ἐπεὶ τὸ γλωσσόκομον εἶχεν Ἰούδας ὅτι λέγει αὐτῷ ὁ Ἰησοῦς Ἀγόρασον ὧν χρείαν ἔχομεν εἰς τὴν ἑορτήν ἢ τοῖς πτωχοῖς ἵνα τι δῷ
Since Judas kept the money bag, some thought that Jesus was telling him to buy what was needed for the feast, or to give something to the poor.
