2-samuel 15:37

Absalom came into Jerusalem - It is very probable that he and his partisans were not far from the city when David left it, and this was one reason which caused him to hurry his departure.

Reader, behold in the case of David a sad vicissitude of human affairs, and a fearful proof of their instability. Behold a king, the greatest that ever lived, a profound politician, an able general, a brave soldier, a poet of the most sublime genius and character, a prophet of the Most High God, and the deliverer of his country, driven from his dominions by his own son, abandoned by his fickle people, and for a time even by his God! See in his desolate state that there is none so exalted that God cannot abase, and none so abased that God cannot exalt. He was forsaken for a time, and his enemies triumphed; God returned, and his enemies were confounded. His crime, it is true, was great and God had declared by Nathan what had now come to pass. God is just, and in numberless instances sees right to show his displeasure even at those sins which his mercy has forgiven. In all cases it is a fearful and bitter thing to sin against the Lord.

15:37 Absalom came, &c. - How soon do royal cities and royal palaces change their masters? But we look for a kingdom which cannot be moved.
