Мегиддо
In [[Mandatory Palestine]], Yeiven was an active member of the [[Jewish Palestine Exploration Society]], serving as its chair between 1944 and 1946. Speaking at a meeting of the society in Tel Aviv in 1934, he celebrated archaeologists' "discovery of Hebrew Palestine" in excavations at [[Tell Beit Mirsim]], [[Tel Megiddo]], and [[Tel Lachish]] in the previous decade. Later he participated in the first "yedi'at ha-Aretz" ("Knowledge of the Land") conference, organised by the society in [[Jerusalem]] in 1943, arguing for the expansion of regional museums to educate Jewish settlers about the antiquities of the country. He also took part in excavations at [[Luxor]] (1924), [[Beit Shean]] (1924–28), [[Seleucia]] (1929–37) and was the co-director, with J. Krause-Marquet, of excavations at [[Ai (Bible)|Ai]] in 1933.
