Jarash was first destroyed by the 30-31 BCE earthquake of Jericho. However, it is more likely that its largest deformation occurred in the year 746 CE and nothing much was left to be considerably affected by later strong earthquakes. Jarash became a city of refuge for fleeing Palestinians, Chritians, or Jews, depending upon politics of the time.

Eusebius and Jerome specify the position of Ramoth-gilead as 15 miles from Amman; one however placing it east and the other west of that place. Ramoth may be Gerasa, the modern Jarash.
