Psalms 88:1-3

LXX2012(i) 1 (89) [A Psalm] of instruction for Aetham the Israelite. I will sing of your mercies, O Lord, for ever: I will declare your truth with my mouth to all generations. 2 For you have said, Mercy shall be built up for ever: your truth shall be established in the heavens. 3 I made a covenant with my chosen ones, I sware to David my servant.
