43:2  G-d now reminds them how He took them on dry land across the Reed Sea and Yarden River, alluding that He will do the same once again.  He tells them how they will endure four different types of exiles - "waters, rivers, fire and flames" - and that throughout all they will remain faithful:  The nations will try to baptize you in their "holy waters," to wash you away from your faith in their "rivers."  They will burn you at the stake for not accepting their faith, but the flames will not touch your soul.  I am with you throughout your ordeals.
