Did the Jews in Our Lord’s time or earlier believe in a form of purgatory?

Purgatory is most often dismissed as being nothing more than a Roman Catholic belief, but does Judaism have a form of purgatory? (ie a place where our remaining sins are purged) or to quote from the Catholic Catechism: > All who die in God's grace and friendship, but still imperfectly > purified, are indeed assured of their eternal salvation; but after > death they undergo purification, so as to achieve the holiness > necessary to enter the joy of heaven. I know that Jews will not call it "purgatory" but I was wondering if this concept or a like-minded concept of purgatory existed within the Jewish faith
