17:21 The Lord says, ‘Be very careful if you value your lives! Do not carry any loads in through the gates of Jerusalem on the Sabbath day.
17:22 Do not carry any loads out of your houses or do any work on the Sabbath day. But observe the Sabbath day as a day set apart to the Lord, as I commanded your ancestors.
