 Zaid and his wife Tzippora were founders of Kibbutz Kfar Giladi in the Galilee, which became a center of Hashomer's underground activity.In 1926, following the establishment of the Haganah, David Ben-Gurion demanded that Hashomer become subordinate to the new organization and transfer its weapons to it.Zaid and his wife supported this move, but most members of Kfar Giladi were opposed to it.
