this canticle is the first part of the song that the three young men sang in the burning fiery furnace. the benedicite is the main part of that song.
this part of the song is sung as a separate canticle, and like the rest of the song, is found in the bible either as an addition to the book of Daniel, in chapter 3, or as a separate book in the apocrypha. the version here is that used by the episcopal church. this canticle is used on tuesday mornings by the episcopal church.
glory to you, Lord God of our fathers;
you are worthy of praise; glory to you.

we will praise you and highly exalt you for ever.
glory to you in the splendor of your temple;
glory to you, beholding the depths;
