Susanna
Susanna is named once, among the women who travel with Jesus and the Twelve and provide for the group from their own resources: "and Joanna the wife of Chuzas Herod's steward, and Susanna, and many others, who were serving them out of their substance" (Lu 8:3).
Among the Women Who Provided for Jesus
Luke introduces the company at the start of a new itinerant phase. Jesus is going through cities and villages proclaiming the kingdom, and with him are the Twelve and a group of women "who had been healed of evil spirits and infirmities" (Lu 8:1-2). The named members are Mary called Magdalene, Joanna the wife of Chuzas Herod's steward, and Susanna; "many others" travel with them as well (Lu 8:3). The text identifies their role plainly — they were "serving them out of their substance" (Lu 8:3). Susanna's name appears nowhere else in the text; her single notice is this place among the women who funded the mission.
