It is probable that this event of Tartar's taking Ashdod, formed an epoch in history, so remarkable, that the year needed not to be recorded. And no doubt that the prophet's going about bare-foot, and without his garment of sackcloth, which he usually wore, made the time also memorable. Isaiah it should seem, while he wore sackcloth, thus preached, by the poverty and mournfulness of his apparel, as well as by his words. But the Lord, his master, will have him now proclaim his truths by type, as well as by preaching. Happy are those servants of the Lord in all ages, whose lives and discourses both tend to glorify God in Christ.
