Is there a law in the Knesset right now to reestablish the Sabbath?
Yes, a bill exists in the Knesset to reestablish the Sabbath, but it has not passed because the secular faction remains too strong. If passed, it would reinstitute shutting everything down on the Sabbath, restricting walking to about half a mile.
Les explains that a law is currently before the Knesset to reestablish the Sabbath, but it has not yet passed because the secular end is still too strong. The bill is there, and if it ever passes, it will reinstitute shutting everything down on the Sabbath, which would mean people could not walk over about half a mile. He connects this to Israel getting closer to being back under the Law and to Jesus' warning in verse 20 to pray that flight not be in winter or on the Sabbath day. If such a law said you could not walk over half a mile, you would not even get out of Jerusalem. So Jesus told them to pray the day to flee would not be on a Sabbath, so they would not be breaking the Law by leaving the several miles required.
