Psalm 24 : 3 - 6

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 righteousness 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.
