'Pray for' in the Bible

Remember [to pray for and help] those who are in prison, as though you [yourselves] were in prison with them. [Remember] those who are being mistreated, realizing that you [yourselves] also share [with them] a physical body [i.e., you are subject to the same kind of trials].

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 I urge you people earnestly to do this [i.e., pray for me], so that I can be sent back to you sooner [i.e., by God's providence].
