Here are some phrases from "Ebenezer," the tune to which "Thy Strong Word" is sung. These same phrases are repeated throughout almost all of the hymn:
The sixth verse is a doxology. The third and fourth lines, sung to the phrases above, are "To Thee, Light of Light begotten, / Praise be sung eternally." The seventh and eighth lines, also sung to the phrases above, are "Mortals, angels, now and ever / Praise the holy Trinity!" "Eternally" and "ever" are both sung with melismas (Ab Bb Ab G F and Ab G F, respectively), musically giving a sense of duration. "Sung" in the fourth line is also sung with a melisma (C Bb) for a similar effect (the verb is modified by "eternally").
