The Rev. Joseph Lowery, a civil rights activist who worked with the late Rev. Martin Luther King Jr., has now become the leader who publicly prays for King’s feuding children.

Lowery gathered with dozens of clergy and civil rights activists at the crypt of King and his wife Coretta Scott King on Tuesday to pray for a peaceful resolution to the legal fight among their kids, The Associated Press reports.

The Rev. Bernice King and her brother, Martin Luther King III, have sued their brother Dexter over their father’s estate. Their sister, Yolanda, died in 2007.
