Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ὥστε, ἀδελφοί μου ἀγαπητοί, ἑδραῖοι γίνεσθε, ἀμετακίνητοι, περισσεύοντες ἐν τῷ ἔργῳ τοῦ κυρίου πάντοτε, εἰδότες ὅτι ὁ κόπος ὑμῶν οὐκ ἔστιν κενὸς ἐν κυρίῳ.
Therefore, my beloved brothers, be steadfast and immovable. Always excel in the work of the Lord, because you know that your labor in the Lord is not in vain.
