Were they ashamed? The Authorized Version certainly meets the requirements of the context; there seems to be an implied interrogation. Most, however, render, "They are brought to shame;" in which ease it seems best to take the verb as a perfect of prophetic certitude, equivalent to "they shall surely be brought to shame."
When; rather, because. Nay, they were not at all ashamed; rather, nevertheless they feel no shame (i.e. at present). They shall be cast down; rather, they shall stumble.
