“They went out.
They proclaimed
The good news
Everywhere.
The Lord worked
With them.
He confirmed
Their message
By the signs
That accompanied it.”
ἐκεῖνοι δὲ ἐξελθόντες ἐκήρυξαν πανταχοῦ, τοῦ Κυρίου συνεργοῦντος καὶ τὸν λόγον βεβαιοῦντος διὰ τῶν ἐπακολουθούντων σημείων.
The climax to this long ending of Mark showed what the disciples of Jesus did after the death, resurrection, and ascension of Jesus. They went out (ἐκεῖνοι δὲ ἐξελθόντες) and preached everywhere (ἐκήρυξαν πανταχοῦ). The Lord worked with them (τοῦ Κυρίου συνεργοῦντος), as he confirmed their message (καὶ τὸν λόγον βεβαιοῦντος) by the signs that accompanied them (διὰ τῶν ἐπακολουθούντων σημείων). The followers of Jesus went about preaching the good news all over the place, while Jesus confirmed their work with signs or miracles.
