Ezekiel 16:45

that lotheth her husband In the sense of the allegory "lothing her husband" should mean changing her god for another; and in the case of Jerusalem and Samaria the charge is intelligible, Jehovah being the husband (ch. 23). But such a charge could hardly be made against the Canaanites, the Hittite mother and Sodom (Jeremiah 2:11). The prophet appears to desert the allegory, introducing real features into his description, and referring to actual adultery and unfaithfulness, which were characteristic of the Canaanite nations. Another interpretation, as old as Theodoret, considers Jehovah to be the "husband" even of the Hittite mother, heathen idolatries being infidelity to the true God. Such a reflexion is not natural to a prophet of this age, though a similar idea occurred to St Paul (Romans 1). At the same time this prophet predicts the restoration of Sodom and its union to the people of the Lord. Cornill, considering the difficulties of interpretation as insuperable, strikes out the words as a gloss.

sister of thy sisters The sisters of Jerusalem were Samaria and Sodom, and she had a genuine family likeness to them.

your mother Your(plur.) refers to the three sisters.
