In 1856 the village was named Bir 'Adas on the map of Southern Palestine that Heinrich Kiepert published that year. In 1870 Victor Guérin noted it as located on a small height, and an Ottoman village list from about the same year showed that Bijar 'Adas had a population of 198 in a total of 60 houses, though that population count included men, only. It was further noted that the name meant "The cistern of lentils". In 1882, the PEF's Survey of Western Palestine described Biyar 'Adas as a village built of adobe bricks, with a well to the east.
In the 1922 census of Palestine, conducted by the British Mandate authorities, Biar Adas had a population of 87, all Muslims, increasing in the 1931 census to 161, still all Muslim, in a total of 28 houses. In the early hours of May 29, 1939, 25 members of the Irgun led by Moshe Moldovsky attacked Biyar 'Adas. They forced their way into two houses and shot deadone man and four women. Two men and a girl were wounded. A letter from Ze'ev Jabotinsky to the Irgun command ordered that the organization must avoid giving the impression that women were being deliberately targeted. In the 1945 statistics the village had a total of 1,604 dunums of land used for citrus and bananas, 3,413 dunums to cereals, 181 dunums were irrigated or used for orchards, while 14 dunams were classified as built-up areas.
1948 and aftermath
The village became depopulated after an assault by the Lehi, an offshoot of the Irgun on April 12, 1948. Later that year, Yosef Weitz set about levelling Biyar 'Adas. After the war the area was incorporated into the State of Israel. The moshav of Adanim was established on village land, southwest of the village site, in 1950. In 1951 another moshav, Elishama, was built on land that had belonged to Biyar 'Adas. Khalidi described the place in 1992:
The site is marked by cactuses, fig trees, palm trees, and the debris of houses. Some houses and sections of houses that were built among citrus groves still stand, deserted, amidst wild vegetation. All are made of concrete and possess a variety of architectural designs, ranging from the elaborate to the simple. Their roofs are flat, slanted, or gabled, and their doors and windows are rectangular. The land in the vicinity is cultivated and is covered in places by Israeli fruit orchards.
