He is speaking of the wars conducted by the Romans in Jerusalem. Not only does He say that there will be wars, but famines and plagues as well, showing that the wrath directed against the Jews is sent by God. For while it can be said that wars are caused by the violence of men, famines and plagues have no other cause than God. Then He says, lest they think that the world will come to an end before they have preached the Gospel, "Be not troubled, the end is not yet." For the destruction of Jerusalem and the end of the whole world will not be at the same time. But "nation shall rise against nation, and kingdom against kingdom," He says, on account of the calamities soon to befall the Jews. And these calamities are the beginning of the pangs of labor; for just as the expectant mother goes into labor but does not give birth yet, so too this present age will first suffer turmoil and wars and then give birth to the things that shall be.
