Josh and Anna Duggar's siblings have taken to social media to support and defend their family members in the wake of the 19 Kids & Counting star's cheating scandal.

On Thursday, Josh publicly confessed to cheating on his wife Anna a day after he was linked to a paid account on extramarital dating site Ashely Madison. Josh released a statement on the family's official website admitting to being unfaithful and calling himself the "biggest hypocrite ever."

The apology also mentioned his previous scandal that involved molesting five underage girls including his sisters Jill (Duggar) Seewald and Jessa (Duggar) Dillard when he was a teenager. That scandal led to TLC canceling 19 Kids & Counting however his sisters have since forgiven Josh and are now appearing supportive of their brother on social media.

Seewald took to Instagram Sunday to preach forgiveness with a photo of an underlined Bible passage entitled "Walk in the Light."

"If we confess our sins, he is faithful, and just to forgive us our sins, and to cleanse us from all unrighteousness," reads the verse.
