The Apostle Paul asks for prayer concerning his missionary journeys

Ephesians 5: 18-20

18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints.
19 Pray also for me, that whenever I open my mouth, words may be given me so that I will fearlessly make known the mystery of the gospel,
20 for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should.

Colossians 4: 2-6

2 Devote yourselves to prayer, being watchful and thankful.
3 And pray for us, too, that God may open a door for our message, so that we may proclaim the mystery of Christ, for which I am in chains.
4 Pray that I may proclaim it clearly, as I should.
5 Be wise in the way you act toward outsiders; make the most of every opportunity.
6 Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.
