Genesis 19:16

And while he lingered— Alarmed at the apprehension of so terrible an event, shocked for the destruction of his relations and friends, and the inhabitants of this devoted city, Lot stood benumbed, as it were, and unable to move, when the angels led him and his family by the hand from the accursed city, and advised him to fly with all speed from the plain, which was destined to ruin, to the mountains, where he would be safe; exhorting him, as a test of his obedience and faith, not to delay at all by looking back, either for the indulgence of a vain curiosity, or with a regretful anxiety for the overthrow of a country, which so justly merited its severe fate. See Luke 9:62.
