The tower in Siloam (ho purgos en Silōam). Few sites have been more clearly located than this. Jesus mentions this accident (only in Luke) of his own accord to illustrate still further the responsibility of his hearers. Jesus makes use of public events in both these incidents to teach spiritual lessons. He gives the “moral” to the massacre of the Galilean pilgrims and the “moral” of the catastrophe at Siloam.
Offenders (opheiletai). Literally, debtors, not sinners as in Luk 13:2 and as the Authorized Version renders here. See note on Luk 7:41; Luk 11:4; Mat 6:12; Mat 18:24-34.
