Gomorrah; Gomorrha

Boyd’s Bible Dictionary:

(submersion). Gomorrha in N. T. A city of the plain destroyed by fire (Gen. 14:1-11; 18:20; 19:24-281And it came to pass in the days of Amraphel king of Shinar, Arioch king of Ellasar, Chedorlaomer king of Elam, and Tidal king of nations; 2That these made war with Bera king of Sodom, and with Birsha king of Gomorrah, Shinab king of Admah, and Shemeber king of Zeboiim, and the king of Bela, which is Zoar. 3All these were joined together in the vale of Siddim, which is the salt sea. 4Twelve years they served Chedorlaomer, and in the thirteenth year they rebelled. 5And in the fourteenth year came Chedorlaomer, and the kings that were with him, and smote the Rephaims in Ashteroth Karnaim, and the Zuzims in Ham, and the Emims in Shaveh Kiriathaim, 6And the Horites in their mount Seir, unto El-paran, which is by the wilderness. 7And they returned, and came to En-mishpat, which is Kadesh, and smote all the country of the Amalekites, and also the Amorites, that dwelt in Hazezon-tamar. 8And there went out the king of Sodom, and the king of Gomorrah, and the king of Admah, and the king of Zeboiim, and the king of Bela (the same is Zoar;) and they joined battle with them in the vale of Siddim; 9With Chedorlaomer the king of Elam, and with Tidal king of nations, and Amraphel king of Shinar, and Arioch king of Ellasar; four kings with five. 10And the vale of Siddim was full of slimepits; and the kings of Sodom and Gomorrah fled, and fell there; and they that remained fled to the mountain. 11And they took all the goods of Sodom and Gomorrah, and all their victuals, and went their way. (Genesis 14:1‑11)
20And the Lord said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous; (Genesis 18:20)
24Then the Lord rained upon Sodom and upon Gomorrah brimstone and fire from the Lord out of heaven; 25And he overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground. 26But his wife looked back from behind him, and she became a pillar of salt. 27And Abraham gat up early in the morning to the place where he stood before the Lord: 28And he looked toward Sodom and Gomorrah, and toward all the land of the plain, and beheld, and, lo, the smoke of the country went up as the smoke of a furnace. (Genesis 19:24‑28); Deut. 29:23; 32:3223And that the whole land thereof is brimstone, and salt, and burning, that it is not sown, nor beareth, nor any grass groweth therein, like the overthrow of Sodom, and Gomorrah, Admah, and Zeboim, which the Lord overthrew in his anger, and in his wrath: (Deuteronomy 29:23)
32For their vine is of the vine of Sodom, and of the fields of Gomorrah: their grapes are grapes of gall, their clusters are bitter: (Deuteronomy 32:32); Matt. 10:1515Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city. (Matthew 10:15); Mark 6:1111And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city. (Mark 6:11)).

Concise Bible Dictionary:

One of the five cities of the plain, or Vale of Siddim, that revolted against Chedorlaomer, who attacked and carried away the people and the spoil. They were rescued by Abraham because Lot was among the captives. The wickedness of the cities being exceedingly great, they were, with the exception of the small city of Zoar, destroyed by fire and brimstone from heaven. SODOM is constantly associated with Gomorrah in the accounts of this destruction, and they are held up both in the Old Testament and in the New Testament as a signal instance of God’s direct action in judgment (Gen. 14; Gen. 18:1919For I know him, that he will command his children and his household after him, and they shall keep the way of the Lord, to do justice and judgment; that the Lord may bring upon Abraham that which he hath spoken of him. (Genesis 18:19); 2 Pet. 2:66And turning the cities of Sodom and Gomorrha into ashes condemned them with an overthrow, making them an ensample unto those that after should live ungodly; (2 Peter 2:6); Jude 77Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire. (Jude 7)). Yet, solemn and complete as was their destruction, the Lord said it would be more tolerable in the day of judgment for these cities than for those where His mighty works had been done, and which had rejected Him (Matt. 10:1515Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city. (Matthew 10:15)).
It is not known where these cities were situated, except that they were near to the Dead Sea: at its north end is now considered to be most probable.
