What happens if you swear on a deceased person's soul and you were lying?

Nothing good ever comes by swearing to GOD and telling lies. My brother swore on his daughter's life that he was telling the truth to his wife that he was not gambling. Then bad things started to happen to their daughter, first her grade went from being a honor student to failing and got kicked out of college, she lost her job, got pregnant then miscarried the baby, almost over dosed on drugs and died, and got arrested for driving under the influence of drugs. It was like somebody put a bad luck spell on her. She was a good kid before the bad luck started. She was not the only one affected by the bad luck, her father lost his job and got kicked out of their house and his wife almost filed for divorce. My brother got to thinking that he cause the bad luck, he went to his priest and asked what he should do. The priest told him to confess to his wife and tell her that he lied about gambling and the priest also told him to swear to god in front of his wife and to tell the truth to GOD and his wife and if he did this GOD would stop punishing him and forgive him. My brother finally did this and their life has gotten better. He found a good job, his daughter is in rehab, and went back to community college.

So you better never lie when you swear to GOD if you do, you and your family will pay the price. Just tell the truth no good ever comes from lying. If you did lie then you better get together with the person you lied to and GOD and tell the truth to both of them and then swear to GOD you are telling the truth. NEVER EVER EVER LIE WHEN YOU SWEAR TO GOD OR ON ANOTHER PERSON LIFE BECAUSE GOD WILL MAKE YOU PAY. I hope this helps you with you question.
