The name Oholibah means "my tent is in her" — God's dwelling is within her. This is the name given to Jerusalem (the southern kingdom of Judah) in Ezekiel 23. Unlike Oholah (Samaria) who had her own tent, Jerusalem was the place where God's own Presence dwelt.
Greater privilege brings greater responsibility and accountability. Oholibah (Jerusalem) sinned more egregiously than her sister Samaria despite being the dwelling place of God's Name. Proximity to the holy does not automatically produce holiness — it amplifies both the blessing of faithfulness and the tragedy of unfaithfulness. Jesus applied this principle in pronouncing greater judgment on Chorazin than Tyre (Matthew 11:21-22).
