The date, nature and significance of the Last Supper has long been a living issue in biblical scholarship, but the issues have taken on a new importance in recent years, due mainly to some of the writings of Mile A. Jaubert,1 who has been working on the Dead Sea Scrolls and whose discoveries go further towards the solution of this problem than anything previously discovered. It is unfortunate, however, that her writings have not been translated into English and have therefore not been widely noticed in this country.2 What we propose to do in this paper is first, to outline again the problem, drawing attention to the main contributions that have been made in recent years; second, to estimate the significance of the problem; and third, to summarise the contribution made by Mlle Jaubert.
