Psalms 17: 1 - 3, 6 - 7
1 Hear a just cause, O LORD; attend to my cry! Give ear to my prayer from lips free of deceit!
2 From thee let my vindication come! Let thy eyes see the right!
3 If thou triest my heart, if thou visitest me by night, if thou testest me, thou wilt find no wickedness in me; my mouth does not transgress.
6 I call upon thee, for thou wilt answer me, O God; incline thy ear to me, hear my words.
7 Wondrously show thy steadfast love, O savior of those who seek refuge from their adversaries at thy right hand.
