The people rejoiced Because this was both an effect of God's grace in them, an eminent token of God's favour to them, and a pledge that this long-desired work would receive a certain and speedy accomplishment. David also rejoiced with great joy To see the work which his heart was so much set upon likely to go on. It is a great reviving to good men, when they are leaving the world, to see those they leave behind them zealous for the work of God.
