Why did Lot’s Wife become a Pillar of Salt?

Genesis 19:26 And [Lot’s] wife looked back behind him, and she became a pillar of salt.

It is popularly thought that Lot’s wife was turned into a pillar of salt for simply looking back at the city of Sodom. But what was so wrong about that?

Let us take a closer look at text of the narrative: Angels came to warn Lot to flee Sodom with his family because they were about to destroy the city for its sinfulness. The angels initially intended to destroy the entire valley with all the cities in it. However, because of Lot’s fear of the mountains, the angels allowed him to escape to the city of Zoar, promising not to destroy that city (Genesis 19:12–22).

From what the angel told Lot in Genesis 19:22, we know that sulfur and fire did not began raining upon the cities until after Lot and his family had reached Zoar. Indeed, Lot and his family reached Zoar in verse 23, and in verses 24–25, the angels began to rain sulfur and fire on the cities as promised. It was only in verse 26 that Lot’s wife “looked back behind him, and she became a pillar of salt.”

Remember that by this time, Lot and his family were already in the safety of Zoar. Therefore, Lot’s wife did more than just “look back” to sneak a peek. The Hebrew word for “looked” in verse 26 is the verb nābaṭ, which means “to gaze; to look intently at”, and carries the nuance of “to regard; to pay attention to”. By choosing this word, the writer wanted to emphasize the attitude of her heart: Even though outwardly she had obeyed the warning to flee from Sodom, inwardly she still held a regard for Sodom, and so she shared the fate of the people of Sodom, even though she herself may not have participated directly in their sinfulness.

Jesus used Lot’s wife as a case study to teach a lesson about how we should regard our lives in this world:

Luke 17:32–33 Remember the wife of Lot. He who seeks his life to save it, shall lose it. ₃₃ He who loses his life shall preserve it.

In context, Jesus was talking about the destruction of Jerusalem, which was going to happen in 40 years time. In verse 31, he urges his followers to flee to the mountains when the time came. In those times, mountains were considered very dangerous places, such that even Lot feared them (Genesis 19:18), yet Jesus says that when that day came, the mountains which Lot feared would be a safer place for them than Jerusalem itself!

When the Roman army surrounded Jerusalem in 70 CE, many people were unwilling to leave their lives in Jerusalem, and so they chose to stay in the city. They were essentially trusting in the Jewish revolutionary forces to defeat the Romans. Unfortunately for them, as history would have it, the Jews lost that war, and those who did not leave Jerusalem were destroyed along with the city.
