Luke's qualification "as was supposed" () avoids stating that Jesus was actually a son of Joseph, since his virgin birth is affirmed in the same gospel. From as early as John of Damascus, the view of "as was supposed of Joseph" regards Luke as calling Jesus a son of Eli—meaning that Heli (, Heli) was the maternal grandfather of Jesus, with Luke tracing the ancestry of Jesus through Mary. Therefore, per Adam Clarke (1817), John Wesley, John Kitto and others the expression "Joseph, [ ] of Heli", without the word "son" being present in the Greek, indicates that "Joseph, of Heli" is to be read "Joseph, [son-in-law] of Heli". There are, however, other interpretations of how this qualification relates to the rest of the genealogy. Some see the remainder as the true genealogy of Joseph, despite the different genealogy given in Matthew.
