'Pray for' in the Bible

"But I say to you, love your enemies, and pray for those who persecute you.

Bless those who curse you, pray for those who calumniate you.

"Nor do I pray for them alone, but for those also who believe in me through their word,

Whenever I pray for you I am continually thanking God, the Father of our Lord Jesus Christ

For this reason from the day I heard of it I have never ceased to pray for you, asking God to fill you with the knowledge of his will with every kind of wisdom and spiritual insight;

Brothers, pray for me.

So confess your sins one to another, and pray for one another, that you may be healed. For the fervent prayer of a righteous man is mighty in its working.
