Hosea 4:15
Though thou, Israel, play the harlot, yet let not Judah offend; and come not ye unto Gilgal, neither go ye up to Beth-aven, nor swear, The LORD liveth. Though thou, Israel, play the harlot, yet let not Judah offend; and come not ye unto Gilgal, neither go ye up to Beth-aven, nor swear, The LORD liveth.
The verse sets forth the state and the spiritual condition of the inhabitants of the land. When Israel plays the harlot, Judah is warned not to follow after into unfaithfulness and idolatrous worship. That condition is connected with the preparation needed for the coming of the Lord.
It exposes those who trample upon God's law by making human laws and forcing the people to accept them, demanding that God's faithful few in number follow the whole world in keeping Sunday according to the laws of the land. It exposes blindness through error from taking words from priests and human lawmakers and supposing it does not matter if the law of God instituted in Eden is not kept. It calls to honor God's memorial given when the foundations of the earth were laid, honoring the living God who made the world in six days and sanctified and blessed the day of His rest.
