There is just a friend who told me of an oath or covenant given to her forcibly by her own husband, now realizing the dangers, she desperately need the oath neutralized.
Does anyone know how to undo this oath.
The oath was performed by digging a hole on the ground.and some water was poured inside it.She was then asked to drink the water after having accepted to adhere to what he asked her of otherwise would die.
Let someone kindly help, I feel sorry for this woman.
