JER 12:16

16 And if the people [of the other nations whose armies have invaded Israel] learn the [religious] customs of my people, and if they learn that I [am listening] when they solemnly promise that they will do something good, like they taught my people to believe that [their god] Baal [was listening] when they made solemn promises, I will cause them to become prosperous, and they also will be my people.
