G5432–φρουρέω–phroureō

In Damascus, the ruler under Aretas the king kept watch over the town of the people of Damascus, in order to take me:

ἐφρούρει ephrourei “was guarding”

But before faith came, we were kept in prison under the law, waiting for the revelation of the faith which was to come.

ἐφρουρούμεθα ephrouroumetha “we were held in custody”

And the peace of God, which is deeper than all knowledge, will keep your hearts and minds in Christ Jesus.

φρουρήσει phrourēsei “will guard”

Who, by the power of God are kept, through faith, for that salvation, which will be seen at the last day.

φρουρουμένους phrouroumenous “[are] being guarded”
