Jeremiah 17:24; Jeremiah 17:27

24 But if you are careful to obey me, declares the LORD, and bring no load through the gates of this city on the Sabbath, but keep the Sabbath day holy by not doing any work on it,

27 But if you do not obey me to keep the Sabbath day holy by not carrying any load as you come through the gates of Jerusalem on the Sabbath day, then I will kindle an unquenchable fire in the gates of Jerusalem that will consume her fortresses.’ ”
