Charles H. Spurgeon on Psalms 128:6

Yea, thou shalt see thy children's children. This is a great pleasure. Men live their young lives over again in their grandchildren. Does not Solomon say that "children's children are the crown of old men?" So they are. The good man is glad that a pious stock is likely to be continued; he rejoices in the belief that other homes as happy as his own will be built up wherein altars to the glory of God shall smoke with the morning and evening sacrifice. This promise implies long life, and that life rendered happy by its being continued in our offspring. It is one token of the immortality of man that he derives joy from extending his life in the lives of his descendants. And peace upon Israel. With this sweet word Psalm 126 was closed. It is a favourite formula. Let God's own heritage be at peace, and we are all glad of it. We count it our own prosperity for the chosen of the Lord to find rest and quiet. Jacob was sorely tossed about; his life knew little of peace; but yet the Lord delivered him out of all his tribulations, and brought him to a place of rest in Goshen for a while, and afterwards to sleep with his fathers in the cave of Machpelah. His glorious Seed was grievously afflicted and at last crucified; but he has risen to eternal peace, and in his peace we dwell. Israel's spiritual descendants still share his chequered conditions, but there remains a rest for them also, and they shall have peace from the God of peace. Israel was a praying petitioner in the days of his wrestling, but he became a prevailing prince, and therein his soul found peace. Yes, all around it is true —"Peace upon Israel! Peace upon Israel."
