Jill, Jinger, Jessa and Jana Duggar may have expressed their feelings about their brother Josh Duggar who was accused of molesting five underage girls, including some of his own sisters, when he was around 14 years old.

In the book titled Growing Up Duggar, the sisters spoke about right and wrong and forgiveness in the chapter 'Your Relationship With Your Sibling'.

The four eldest Duggar daughters were talking about brother-sister relationships, but Perez Hilton suspects that their writings are hinting at the molestation ordeals, that at least on them have suffered at the hand of their eldest brother.

Some excerpts about forgiveness from the book that was released in 2014 reads: "Even though we may not feel like forgiving someone, we must choose to forgive every person who offends us and do it before they ask — and regardless if they ever do ask.

"The choice to forgive doesn't always free the other person from the consequences of his or her wrong actions, but it frees the forgiver of negative feelings towards the offender. And if we still have feelings of bitterness, the Bible says it's not only to forgive the other person, but also to go a step further and look for ways to bless him or her."

TLC, meanwhile, has pulled its super-hit reality series about the evangelical Christian family, but the network is yet to cancel the series and terminate the contracts with Jim Bob and Michelle Duggar.

The sexual abuse was reported to the police only in December 2006 when someone called a hotline and disclosed that Josh had molested several minor girls three and a half years before.

However, Rumours are abuzz that the controversial network is planning a spinoff series to follow the lives of Jill and Jessa as they continue to grow their family.

The parents, Jim Bob and Michelle faced sharp criticism as they kept quiet about the entire issue for years until the matter was registered with the Arkansas police.

Last month, Jill delivered her son Israel David with husband Derick Dillard and Jessa is four months pregnant with husband Ben Seewald.

As major advertisers have started pulling out of the controversial reality show about the Duggar family, TLC may try to bring the viewers back by showing the daughters, some of whom might be the victims of Josh.
