Verse 12. That - This mercy I beg not only for my own sake, but for the sake of thy people, that they may enjoy those blessings which thou hast promised them; and particularly, that our sons, who are the strength and hopes of a nation, may be like plants, flourishing and growing in height and strength, as plants do in their youth; for when they grow old, they wither and decay. Cornerstone - Strong and beautiful.
Verse 14. Breaking in - Of enemies invading the land, or assaulting our cities, and making breaches in their walls. Going out - Of our people, either out of the cities to fight with an invading enemy: or out of the land into captivity.
