Will Israel rebuild the temple before too long?
Yes, according to the context, everything is getting set in the nation of Israel, and they will, before too long, have the temple. In that temple worship they will institute the Sabbath day, shutting down nightclubs, movies, entertainment, and business to establish the Sabbath.
Les explains that the secular Jews want nothing of it, but the religious Jews have almost mandated that they've got to go back and keep the Sabbath. Everything is getting set in the nation of Israel, where they will, before too long, have the temple, and in temple worship they will institute the Sabbath day. This will mean shutting down nightclubs, movies, entertainment, and business to establish the Sabbath. Present-day Judaism limits Sabbath walking distance to about a mile or a mile and a half, though the Mosaic law originally did not, in Les's view. Jesus references this when telling them to pray their flight does not happen on a Sabbath, because it will be like leaving Israel the night of the Passover, requiring miraculous movement as in the exodus from Egypt. This occurs at the midpoint of the Tribulation when Jews in Jerusalem realize the one they trusted, who signed a treaty three and a half years earlier, is their mortal enemy. There will also be a tremendous earthquake in chapter 11 that same day, and these Jews will congregate and make their flight out of Jerusalem, a mixed remnant.
