A.T. Robertson Commentary Acts 14:26

"and thence they sailed to Antioch, from whence they had been committed to the grace of God for the work which they had fulfilled." — Acts 14:26 (ASV)

They sailed away to Antioch (απεπλευσαν εις Αντιοχειαν). Effective aorist active indicative of αποπλεω, to sail off. They had been gone some eighteen months.

They had been committed (ησαν παραδεδομενο). Periphrastic past perfect passive of παραδιδωμ, old and common verb. High and serious thoughts filled the hearts of these first returned missionaries as they neared home. The grace of God had been with them. They had fulfilled (επληρωσαν) the work to which they had been set apart by the Holy Spirit with the prayers of the Antioch church. They now had a wondrous story to tell.
