(excerpt)
Ezekiel refers back to Israel’s mixed parentage in Canaan to introduce two sisters of the prostitute (who, in Ezekiel’s time was identified with Judah’s capital Jerusalem). The two sisters were the cities Samaria (capital of the former northern kingdom) and Sodom. Both cities were destroyed by God’s judgment, but Jerusalem’s sin was worse than both (44-48). Sodom was well known for its greed and immorality, Samaria for its idolatry, but both cities now appeared righteous compared with Jerusalem. Surely, the destruction of Jerusalem was inescapable (49-52).
Samaria and Sodom may each have had some satisfaction in seeing Jerusalem suffer the same fate as they had suffered. Yet all three had hope for the future. After the overthrow of Babylon, the three regions of Palestine represented by these three cities would be restored and inhabited again (53-55). In the meantime Jerusalem had to bear the shame of its immoral behaviour. In times past, Jerusalem was ashamed to mention the sin of Sodom, but now her reputation was just as bad (56-58).
