SANCTIFICATION OF GOD: We will sanctify Your name in this world just as it is sanctified in the highest heavens, as it is written by Your prophet: And they call out to one another and say: Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory. Blessed be the Presence of the LORD in His place. In Your Holy Words it is written, saying, The LORD reigns forever, Your God, Oh Zion, throughout all generations. Hallelujah. Throughout all generations, we will declare Your greatness, and to all eternity we will proclaim Your holiness. Your praise, Our God, shall never depart from our mouth, for You are a great and holy God and King. Blessed are You, Oh Lord, the Holy God. You are holy, and Your name is holy, and holy beings praise You daily. Blessed are You, Oh Lord, the Holy God.
