The Duggars returned to television on Sunday night for the first time since it was revealed that the family's eldest son Josh molested five girls, including sisters Jill and Jessa, and that he repeatedly cheated on his wife. But in the first installment of the three-part special,Jill & Jessa: Counting On, Jill and Jessa say they've forgiven their brother.

"So the police report was released to the world. And I know that wasn't right," Jill said of the news of Josh's abuse getting out. "We had to work through it because as a victim, you've already worked through that — you've already dealt with it and you've already moved on. And you don't want that rubbed in your face all the time and for everybody else to see."

The Duggars get emotional over how Josh's "secret life" hurt them

The family did their best to move on and heal, with Jill and Jessa even defending Josh during an interview with Fox New's Megyn Kelly earlier this year. However, they soon found themselves blindsided by the revelation of Josh's extramarital affairs and pornography addiction.

"It was one thing months before when we looked back on the situation that happened when he was a teenager and saying that was so long ago, but here's something present-day. This is an issue that's happening right now," Jessa said. "It was really difficult to come to grips with that."

Jill said she felt betrayed by Josh allowing her and Jessa to defend him without completely coming clean to the family. "[My husband] Derick and I talked about how earlier this year when Jess and I were talking with Megyn Kelly, we wanted to say the truth, and I feel like we did that," she said. "Looking back, I still would have done that — I still would have said the truth of what happened — but knowing now what Joshua was hiding, I feel like it wasn't right for him to let us speak our words without having the full knowledge of what he was hiding."
