God shall bless us; and all the ends of the earth shall fear him. God shall bless us - He shall ever be speaking good to us, and ever showering down good things upon us.
The last clause of the sixth verse should be joined to the seventh, as it is in several of the Versions, and should be in all. Many of the fathers, and several commentators, have thought that there is a reference to the Holy Trinity in the triple repetition of the word God: "God, our God, shall bless us; God shall bless us;" thus paraphrased in the old Psalter: "Blis us God the Fader: and our God the sone: and blis us and multipli us God the Hali Gast; that swa drede him God, all the endis of erth; for he wil comme to deme rightwysly that unrightwysly was demed. He that kan drede him, he eesses noght to lufe him."
When or by whom this Psalm was written cannot be ascertained. It seems to be simply a prophecy concerning the calling of the Gentiles, the preaching of the apostles, and the diffusion and influence of Christianity in the world. It is a fine piece of devotion; and it would be nearly impossible to read or repeat it with a cold and unaffected heart.
