Jeremiah 17:27

Jeremiah 17:27 But if you do not listen to Me to sanctify the Sabbath day and not to bear a burden when coming in through the gates of Jerusalem on the Sabbath day, then I will kindle a fire in its gates, and it will devour the palaces of Jerusalem and will not be extinguished.

the Sabbath signifies that God has done everything, completed everything, and prepared everything and that man must stop all his work. To work on the Sabbath is an insult to God and to what He has accomplished. Instead of working in such a way, we should take in God as our enjoyment, drinking of Him as the fountain of living waters. To sanctify God's Sabbath is to stop our work and to take what God has done for us.
