For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. For when they shall say, Peace and safety - This points out, very particularly, the state of the Jewish people when the Romans came against them; and so fully persuaded were they that God would not deliver the city and temple to their enemies, that they refused every overture that was made to them.
Sudden destruction - In the storming of their city and the burning of their temple, and the massacre of several hundreds of thousands of themselves; the rest being sold for slaves, and the whole of them dispersed over the face of the earth.
As travail upon a woman - This figure is perfectly consistent with what the apostle had said before, viz.: that the times and seasons were not known: though the thing itself was expected, our Lord having predicted it in the most positive manner. So, a woman with child knows that, if she be spared, she will have a bearing time; but the week, the day, the hour, she cannot tell. In a great majority of cases the time is accelerated or retarded much before or beyond the time that the woman expected; so, with respect to the Jews, neither the day, week, month, nor year was known. All that was specifically known was this: their destruction was coming, and it should be sudden, and they should not escape.
