Adam Clarke on 1 Samuel 5:9

The hand of the Lord was against the city - As it was at Ashdod, so it was at Gath. The Vulgate says, Et computrescebant prominenter extales eorum; which conveys the idea of a bloody flux, dysentery, and ulcerated anus; and it adds, what is not to be found in the Hebrew text, nor many of the versions, except some traces in the Septuagint, Et fecerunt sibi sedes pelliceas, "And they made unto themselves seats of skins;" for the purpose of sitting more easy, on account of the malady already mentioned.
