Limbus Patrum.
The half-way house between earth and heaven, where the patriarchs and prophets, after death, await the coming of Messiah. According to the Roman Catholic notion, this is the hell, or hads, into which Jesus Christ descended after He gave up the ghost on the cross. Limbo, and sometimes Limbo patrum, is used for quod, jail, confinement.
