as you cooperate by praying for us. Then, many people will give thanks [to God] on our behalf for the gift He has given to us through [your] many [prayers].
For I know that, through your requests [in prayer] for me and the help provided by the Holy Spirit of Jesus Christ, this situation will result in my being rescued [i.e., released from imprisonment].
For everything [i.e., that we have experienced. See verses 8-12] is for your sakes so that [God’s] unearned favor, being extended to so many, [in bringing them salvation through Paul’s ministry] may result in much thanksgiving in praise to God.
At the same time, pray for us also, that God will open up a door [of opportunity] for [proclaiming] the message, so we can tell about the [previously] hidden secret of Christ, for which I have also been imprisoned.
Pray for us [continually]. We are convinced that we [i.e., the writer of Hebrews] have a clear conscience [i.e., regarding our relationship to you] and we want to behave properly in every way.
And another thing: Prepare a place for me to stay, because I hope that through [an answer to] your prayers I will be returned to you. [Note: Paul was hoping to be released from imprisonment to visit Philemon at Colosse].
