The Apostle Paul
Colossians 4:3BSB·traditional attribution

as you pray also for us, that God may open to us a door for the word, so that we may proclaim the mystery of Christ, for which I am in chains.

John Calvin Reformed @genevareformer

3. Pray also for us. He does not say this by way of pretense, but because, being conscious to himself of his own necessity, he was earnestly desirous to be aided by their prayers, and was fully persuaded that they would be of advantage to them. Who then, in the present day, would dare to despise the intercessions of brethren, which Paul openly declares himself to stand in need of?

Matthew Henry Presbyterian @wholebiblehenry

If this be considered as connected with the foregoing verse, then we may observe that it is part of the duty which masters owe their servants to pray with them, and to pray daily with them, or continue in prayer.

Withal, praying also for us,.... The persons to be prayed for are next directed to; and these are not only themselves, though their concern is very near and great, but others also, all the saints and people of God, yea, all men, and in particular the ministers of the Gospel.
