(Before It's News)
1 The earth is the LORD’s and the fulness thereof, the world and those who dwell therein;
2 for he has founded it upon the seas, and established it upon the rivers.
3 Who shall ascend the hill of the LORD? And who shall stand in his holy place?
4 He who has clean hands and a pure heart, who does not lift up his soul to what is false, and does not swear deceitfully.
5 He will receive blessing from the LORD, and vindication from the God of his salvation.
6 Such is the generation of those who seek him, who seek the face of the God of Jacob. [Selah]
