Jeremiah 6:25

Go not forth into the field, nor walk by the way; for the sword of the enemy and fear is on every side.

The warning is clear in its awful denunciation against sin. It carries sorrow of heart over the people's transgression. It makes a touching appeal to return to God, which the mass of the people failed to answer. It belongs to prophecy showing that the North was the region from which ungodly enemies and oppressors of God's people came, and in Ezekiel's last-day prophecy such northern enemy imagery represents the forces of world evil opposed to God and his redeemed people.

In these last days God is calling out a people. Those who are called out are to keep the whole law. Keeping the whole law includes keeping the Sabbath.
