Adam Clarke on 1 Samuel 12:25

Ye shall be consumed - If ye do wickedly you shall be destroyed, your kingdom destroyed, and your king destroyed. Here they had set before them life and good, death and evil. Never was a people more fully warned, and never did a people profit less by the warning; and they continue to this day monuments of God's justice and forbearance. Reader, What art thou? Perhaps a similar monument. Consider therefore what great things God has done for thee.
