Biblical Account:
The account of Lot's wife turning into a pillar of salt is found in the Book of Genesis, specifically in Genesis 19:15-26. This event occurs during the destruction of Sodom and Gomorrah, two cities known for their wickedness. God, in His judgment, decides to destroy these cities but shows mercy to Lot, Abraham's nephew, and his family by allowing them to escape.

As the angels urge Lot and his family to flee the city and not look back, they say, "Flee for your lives! Do not look back, and do not stop anywhere in the plain! Flee to the mountains, or you will be swept away!" (Genesis 19:17). Despite this clear command, Lot's wife disobeys. Genesis 19:26 states, "But Lot’s wife looked back, and she became a pillar of salt."

Theological Significance:

The account is often interpreted as a warning against the dangers of attachment to worldly possessions and sinful lifestyles. It underscores the necessity of wholehearted commitment to God's will and the perils of divided loyalties.
