1 Thessalonians 3:5
Nestle 1904 Greek New Testament · Berean Standard Bible
διὰ τοῦτο κἀγὼ μηκέτι στέγων ἔπεμψα εἰς τὸ γνῶναι τὴν πίστιν ὑμῶν μή πως ἐπείρασεν ὑμᾶς ὁ πειράζων καὶ εἰς κενὸν γένηται ὁ κόπος ἡμῶν
For this reason, when I could bear it no longer, I sent to find out about your faith, for fear that the tempter had somehow tempted you and that our labor might have been in vain.
