Who Are Ohola and Ohilibah?

I have been reading through the book of Ezekiel lately and came across an interesting passage in chapter 23. In chapter 23 the message to Ezekiel is one of comparison. God compares Samaria and Jerusalem, the Northern and Southern kingdoms of Israel, to two sisters. These two sisters(Ohola and Ohilibah) have turned into prostitutes.
The whole chapter is filled with rather intense and graphic descriptions of how grievous the behavior of these two sisters has become. Of course the comparison is vivid. These two sisters are how God’s people have treated Him. They have repeatedly turned from Him. They have time and again gone and worshiped false gods. God compares turning away from Him and worshiping false gods to adultery.
Most often we think of adultery as an individual sin. One person commits adultery with another. The law was clear that when an individual committed adultery the penalty was death.
Here in Ezekiel God makes it clear that the sin of adultery can have a corporate expression. The people as a whole have turned their backs on God and been unfaithful. They are an adulterous people. They have not been faithful to the One who has chosen them, loved them, provided for them, and cared for them. They have played the prostitute.
And Ezekiel gives them the warning. The penalty for an individual that is guilty of adultery will also be the penalty for the nation that commits adultery. The Babylonians are coming and bring the judgment of God. Many will die, and many will be carted off to a foreign land.
This text makes me think of faithfulness on two levels. Am I personally being fully faithful to the Lord Jesus Christ? No one else has done what He has done. No one else shed their blood and died for my sins. Therefore, no one else is worthy of my utmost devotion and surrender. But, do I always give it to Him? No. May the Lord continue to work in me to bring me further and further down the road of complete surrender.
This also applies to the church as a whole. Are we as a collective group being faithful to the One who redeemed us at such a cost? Are we guilty of collective sins? Then we need to seek repentance.
