Revelation 5:8

 Now when He had taken the scroll, the four living creatures and the twenty-four elders fell down before the Lamb, each having a harp, and golden bowls full of incense, which are the prayers of the saints.

Psalm 141:2  Let my prayer be set before You as incense, the lifting up of my hands as the evening sacrifice.

1 Timothy 2:1  Therefore I exhort first of all that supplications, prayers, intercessions, and giving of thanks be made for all men.
