Many passages...
"Open thou mine eyes, that I might behold wondrous things out of thy law..."
"Search me and know my heart, try me and know my thoughts..."
"Who can understand his errors? Cleanse thou me from secret faults."
From
Matthew 10:1, I pray for power against unclean spirits and for healing.
Isaiah 11:2-3...I pray for those seven anointings on the Messiah.
Psalm 139:23-24
Those are a few I pray from regularly.
More coming...
