The most contested textual variant in Mark 1:40-45 is whether Jesus was filled with compassion for the leper (σπλαγχνισθείς) or with anger (όργισθείς). Using quantitative narrative analysis (QNA), the article addresses the issue of the lectio difficilior for this variant. Three manuscripts (Bezae, Vaticanus, and Washingtonianus) are analysed to determine the distinctive Tendenz of each for this story. Codices D and W present the story in opposite ways but have parallel tendencies when it comes to plot and characterisation. On the other hand, B presents a more complex and variegated plot and characterisations which suggest that B contains the lectio difficilior. This narrative approach can serve textual critics as another way to approach internal arguments.
