NET

27 But you must obey me and set the Sabbath day apart to me. You must not carry any loads in through the gates of Jerusalem on the Sabbath day. If you disobey, I will set the gates of Jerusalem on fire. It will burn down all the fortified dwellings in Jerusalem and no one will be able to put it out.’”

Darby

27 But if ye will not hearken unto me, to hallow the sabbath day and not to bear a burden and enter in through the gates of Jerusalem on the sabbath day, then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.

KJV

27 But if ye will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.
