1 Timothy 2:1-4:
"First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men, for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way. This is good, and it is acceptable in the sight of God our Savior, ..."
Likewise, St Paul asked that prayers be offered on his behalf:
Romans 15:30
I appeal to you, brethren, by our Lord Jesus Christ and by the love of the Spirit, to strive together with me in your prayers to God on my behalf.
Amen.
