Psalm 139:1-3 O Lord, You examine me and know me. You know when I sit down and when I get up; even from far away you understand my motives. You carefully observe me when I travel or when I lie down to rest; You are aware of everything I do. 

Revelation 3:7b This is the solemn pronouncement of the Holy One, the True One, who holds the key of David, who opens doors no one can shut, and shuts doors no one can open.
