We are commanded to pray for others:

"You have heard that it was said, 'Love your neighbor and hate your enemy.' But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven" - Matthew 5:43-45a.

"Devote yourselves to prayer, being watchful and thankful. 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. Pray that I may proclaim it clearly, as I should" - Colossians 4:2-4.

"I urge, then first of all, that requests, prayers, intercession and thanksgiving be made for everyone - for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. This is good, and pleases God our Savior who wants all men to be saved and to come to a knowledge of the truth. … I want men everywhere to lift up holy hands in prayer, without anger or disputing" - 1 Timothy 2:1-4, 8.

We are also given examples of praying for others:

"Epaphras, who is one of you and a servant of Christ Jesus, sends his greetings. He is always wrestling in prayer for you, that you may stand firm in all the will of God, mature and fully assured" - Colossians 4:12.

"I have not stopped giving thanks for you, remembering you in my prayers. I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. I pray also that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in the saints, and his incomparably great power for us who believe" - Ephesians 1:16-19a.

"For this reason I kneel before the Father, from whom his whole family in heaven and on earth derives its name. I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, may have power, together with all the saints, to grasp how wide and long and high and deep is the love of Christ, and to know this love that surpasses knowledge - that you may be filled to the measure of all the fullness of God. Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us, to him be glory in the church and in Christ Jesus through out all generations, for ever and ever! Amen" - Ephesians 3:14-21.
