15Blessed is the people that know the joyful sound: they shall walk, O LORD, in the light of thy countenance. 16In thy name shall they rejoice all the day: and in thy righteousness shall they be exalted. 17For thou art the glory of their strength: and in thy favour our horn shall be exalted. 18For the LORD is our defence; and the Holy One of Israel is our king.19Then thou spakest in vision to thy holy one, and saidst, I have laid help upon one that is mighty; I have exalted one chosen out of the people. 20I have found David my servant; with my holy oil have I anointed him: 21With whom my hand shall be established: mine arm also shall strengthen him.
