Genesis 19:23 WEB

²¹  He said to him, 'Behold, I have granted your request concerning this thing also, that I will not overthrow the city of which you have spoken.

²²  Hurry, escape there, for I can't do anything until you get there.' Therefore the name of the city was called Zoar.{Zoar means 'little.'}

²³  The sun was risen on the earth when Lot came to Zoar.

²⁴  Then Yahweh rained on Sodom and on Gomorrah sulfur and fire from Yahweh out of the sky.

²⁵  He overthrew those cities, all the plain, all the inhabitants of the cities, and that which grew on the ground.
