Or those eighteen - Jesus himself adds another similar case, to warn them - a case which had probably occurred not long before, and which it is likely they judged in the same manner.

Upon whom the tower in Siloam fell - The name Siloah or Siloam is found only three times in the Bible as applied to water - once in Isaiah 8:6, who speaks of it as running water; once as a pool near to the king's garden in Nehemiah 3:15; and once as a pool, in the account of the Saviour's healing the man born blind, in John 9:7-11. Josephus mentions the fountain of Siloam frequently as situated at the mouth of the Valley of Tyropoeon, or the Valley of Cheesemongers, where the fountain long indicated as that fountain is still found. It is on the south side of Mount Moriah, and between that and the Valley of Jehoshaphat. The water at present flows out of a small artificial basin under the cliff, and is received into a large reservoir 53 feet in length by 18 feet in breadth. The small upper basin or fountain excavated in the rock is merely the entrance, or rather the termination of a long and narrow subterranean passage beyond, by which the water comes from the Fountain of the Virgin. For what purpose the "tower" here referred to was erected is not known; nor is it known at what time the event here referred to occurred. It is probable that it was not far from the time when the Saviour made use of the illustration, for the manner in which he refers to it implies that it was fresh in the recollection of those to whom he spoke.

The tower in Siloam - This tower was probably built over one of the porticoes near the pool, which is mentioned John 9:7. See also Nehemiah 3:15.

Debtors, οφειλεται, a Jewish phrase for sinners. Persons professing to be under the law are bound by the law to be obedient to all its precepts; those who obey not are reckoned debtors to the law, or rather to that Divine justice from which the law came. A different word is used when speaking of the Galileans: they are termed ἁμαρτωλοι, as this word is often used to signify heathens; see the notes on Luke 7:37; it is probably used here in nearly a similar sense. "Do ye who live in Jerusalem, and who consider your selves peculiarly attached to the law, and under the strongest obligations to obey it - do ye think that those Galileans were more heathenish than the rest of the Galileans, because they suffered such things? No. It was not on this account that they perished: both these cases exhibit a specimen of the manner in which ye shall all perish, if ye do not speedily repent, and turn to God."

Or those eighteen,.... Men; the Persic version reads, "those twelve"; but all copies, and other versions, agree in this number:

upon whom the tower in Siloam fell, and slew them; there was a pool near Jerusalem, called the Pool of Siloam, John 9:7 near, or over which, was a tower built, which fell down and killed eighteen men; very likely as they were purifying themselves in the pool, and so was a case very much like the other, and might be a very late one: and this Christ the rather observes, and puts them in mind of, that they might see that not Galileans only, whom they had in great contempt, but even inhabitants of Jerusalem, died violent deaths, and came to untimely ends; and yet, as not in the former case, so neither in this was it to be concluded from hence, that they were sinners of a greater size, or their state worse than that of other men:

think ye that they were sinners; or debtors; for as sins are called debts, Matthew 6:12 so sinners are called debtors:

above all men that dwelt in Jerusalem? there might be, and doubtless there were, as great, or greater sinners, in that holy city, and among such that made great pretensions to religion and holiness, as they were.

Sinners (ὀφειλέται)

Lit., debtors. Possibly with reference to the figure at the close of the last chapter. Compare Matthew 5:25; Matthew 6:12; Matthew 18:24; Luke 11:4.

Or those eighteen, upon whom the tower in {b} Siloam fell, and slew them, think ye that they were sinners above all men that dwelt in Jerusalem?

(b) That is, in the place, or river: for Siloam was a small river from which the conduits of the city came; see Joh 9:7 Isa 8:6; and therefore it was a tower or a castle, built upon the conduit side, which fell down suddenly and killed some.

13:4,5 Those eighteen, upon whom the tower of Siloam fell. Nothing is known of the incident. The lesson is the same as before. These did not perish because they were greater sinners. All must repent or perish. Siloam was a suburb of Jerusalem, south of the city.

sinners: or, debtors

4, 5. tower in Siloam-probably one of the towers of the city wall, near the pool of Siloam. Of its fall nothing is known.

13:1-5 Mention was made to Christ of the death of some Galileans. This tragical story is briefly related here, and is not met with in any historians. In Christ's reply he spoke of another event, which, like it, gave an instance of people taken away by sudden death. Towers, that are built for safety, often prove to be men's destruction. He cautioned his hearers not to blame great sufferers, as if they were therefore to be accounted great sinners. As no place or employment can secure from the stroke of death, we should consider the sudden removals of others as warnings to ourselves. On these accounts Christ founded a call to repentance. The same Jesus that bids us repent, for the kingdom of heaven is at hand, bids us repent, for otherwise we shall perish.
