13:20 The elect - The Christians: whom he hath chosen - That is, hath taken out of, or separated from, the world, through sanctification of the Spirit and belief of the truth. He hath shortened - That is, will surely shorten.
13:14-23 The Jews in rebelling against the Romans, and in persecuting the Christians, hastened their own ruin apace. Here we have a prediction of that ruin which came upon them within less than forty years after this. Such destruction and desolation, that the like cannot be found in any history. Promises of power to persevere, and cautions against falling away, well agree with each other. But the more we consider these things, the more we shall see abundant cause to flee without delay for refuge to Christ, and to renounce every earthly object, for the salvation of our souls.
