The versification of prose NARRATIVE has always been of interest to Persian language poets. One of the most important courses of versification of religious NARRATIVE in Iran, which has attracted no attention yet, is that of old testament NARRATIVE story. In this process, some adjuncts are added to the prose NARRATIVEs. In this study, however, some of NARRATIVE poems from the old testament, namely, The Letter of Moses and Joseph and Zuleikha by Shahin Shirazi, and Aqidat-Yashaq by Molla Aminahave been analyzed and the causality patterns of these adjuncts extracted. The results imply that the causality pattern of these adjuncts show interpretive, expansive, and associative patterns. In interpretation pattern, the cause of one vague event is expressed through real and sometimes superfine events. In developmental pattern, some adjuncts like destiny and the companionship of God with his prophets, physical features, spiritual features and misery are added to the context. In associative pattern, the association between a part and a similar whole has been used. Since all of these patterns are used in the old testament, it is likely that later poets have adopted such patterns. Finally, it should be mentioned that such adjuncts are to persuade and direct the reader, not merely to have a creative and literary NARRATIVE.
