His Name shall endure forever (comp. Psalms 45:2, Psalms 45:6; Psalms 102:12; Isaiah 9:7). "The eternity of the Name is based upon the eternity of the kingdom" (Hengstenberg). His Name shall be continued as long as the sun (comp. Psalms 72:5); or, his Name shall be renewed—shall spring again to fresh life. Dr. Kay compares an expression of Renan's, "Son culte se rajeunira." And men shall be blessed in him; literally, men shall bless themselves in him (comp. Genesis 22:18; Genesis 26:4). All nations shall call him blessed. With these words the psalm, properly speaking, ends. The doxology (Psalms 72:18, Psalms 72:19) and the note (Psalms 72:20) were probably appended by the arranger of the book.
Blessed be the Lord God, the God of Israel (compare the other doxologies, which begin similarly (Psalms 41:13; Psalms 89:52; Psalms 106:42). Who only doeth wondrous things (comp. Psalms 86:8, Psalms 86:10; and Job 5:9). And blessed be his glorious Name forever (comp. Psalms 29:2; Psalms 34:3; Psalms 46:2; Psalms 69:30; Psalms 113:2, etc.). And let the whole earth be filled with his glory. The whole earth can no otherwise be filled with the glory of God, than by men everywhere glorifying him, and bowing clown in adoration before his Son. The promise had been made that so it should one day be (Numbers 14:21); and the psalmist anticipates the fulfilment of the promise. Amen, and Amen (comp. Psalms 41:13; Psalms 89:52; Psalms 106:48).
