2 Samuel 15:14

Arise, and let us flee— As the danger was instant, David took his measures accordingly. The city was not in a condition to sustain a siege; and if it were, he did not care to expose a favourite city, built by himself, and the residence of the tabernacle of God, to all the evils incident to sieges, and almost inseparable from them. Nor, perhaps, did he care to trust the inhabitants of a place so long exposed to the taint of Absalom's temptations; see Psalms 55. Well acquainted with the young man's impetuosity, and the madness of the people, David judged it much better to give way to the fury of the flood, than attempt to stem it in the fullness of its overflowing.
