And one cried to another, and said, (h) Holy, holy, holy, [is] the LORD of hosts: the whole (i) earth [is] full of his glory.
(h) This often repetition signifies that the angels cannot satisfy themselves in praising God, to teach us that in all our lives we should give ourselves to the continual praise of God.
(i) His glory not only appears in the heavens but through all the world, and therefore all creatures are bound to praise him.
