Luke 13:4

ἐκεῖνοι οἱ δεκαοκτώ, ἐφ' οὓς ἔπεσεν ὁ πύργος ἐν τῷ Σιλωάμ. It is an ingenious, but of course uncertain conjecture of Ewald, that the death of these workmen was connected with the notion of retribution because they were engaged in building part of the aqueduct to the Pool of Siloam, for the construction of which Pilate had seized some of the sacred Corban-money (Mark 7:11; Jos. B. J. II. 9, § 4).

Σιλωάμ. The pool (John 9:7; Isaiah 8:6), near the village of Silwân, at the entrance of the Tyropoeon valley, which runs into the Valley of Jehoshaphat between Sion and Moriah.

ὅτι αὐτοὶ ὀφειλέται ἐγένοντο. ‘That they themselves proved themselves to be debtors.’ (Wyclif, Rhem. and Vulg[276] debitores.)

[276] Vulg. Vulgate.
