Charles H. Spurgeon on Psalms 107:20

He sent his word. The same expression occurs in Ps 147:15,18; compare Isa 55:11. We detect in such passages the first glimmering of St. John's doctrine of the agency of the personal Word. The Word by which the heavens were made, Ps 33:6, is seen to be not merely the expression of God's will, but his messenger mediating between himself and his creatures. It is interesting to compare with this the language of Elihu in the parallel passage of Job 33:23, where what is here ascribed to the agency of the Word is ascribed to that of the "mediating angel, or messenger." —J.J. Stewart Perowne.
