Charles Ellicott Commentary Ezekiel 23:4

"And the names of them were Oholah the elder, and Oholibah her sister: and they became mine, and they bare sons and daughters. And as for their names, Samaria is Oholah, and Jerusalem Oholibah." — Ezekiel 23:4 (ASV)

Samaria is Aholah, and Jerusalem Aholibah. —Samaria, as the capital, represents the northern kingdom and is called Aholah, meaning her own tabernacle, because she established her own worship instead of resorting to the Temple; while the southern kingdom, represented by Jerusalem, is called Aholibah, meaning my tabernacle is in her, because she still contained the sanctuary of the Lord. The word “elder” should be translated greater, as in Ezekiel 16:46. (See Note there.)
