Psalms 128:5

The Lord shall bless thee out of Zion
The church of God, where he dwells, out of which he shines, even the Word of the Lord, as the Targum in the king's Bible; and where he commands his blessings of grace to descend on his people, even life for evermore, ( Psalms 133:3 ) . Here he blesses them with his word and ordinances, which are the goodness and fatness of his house, and with his presence in them; so that the man that fears God is blessed, not only in his person, and in his family, but in the house of God; see ( Psalms 118:26 Psalms 118:27 ) ;

and thou shall see the good of Jerusalem all the days of thy life;
the goodness of God in Jerusalem, which is another name for the church of God; the beauty of the Lord in his house and ordinances; his power and his glory in the sanctuary: or should see the church of God in prosperous circumstances all his days; true religion flourish, the power of godliness in the professors of it; the word and ordinances blessed to the edification of saints, and many sinners converted and gathered in. This may be applied to Christ, ( Isaiah 53:11 ) .
