Admah

The border of the Kena‘ani was from Tzidon, as you go toward G’rar, to ‘Azah; as you go toward S’dom, ‘Amora, Admah and Tzvoyim, to Lesha.

they made war together against Bera king of S'dom and against Birsha king of 'Amora, Shin'av king of Admah, Shem'ever king of Tzvoyim, and the king of Bela (which is the same as Tzo'ar).

Then the kings of S'dom, 'Amora, Admah, Tzvoyim and Bela (that is, Tzo'ar) came out and arrayed themselves for battle in the Siddim Valley

and that the whole land has become burning sulfur and salt, that it isn't being sown or bearing crops or even producing grass - like the overthrow of S'dom, 'Amora, Admah and Tzvoyim, which ADONAI overthrew in his furious anger -

Efrayim, how can I give you up, or surrender you, Isra'el? How could I treat you like Admah or make you like Tzvoyim? My heart recoils at the idea, as compassion warms within me.
