He also began began a new edition of Hebrew and English Maḥzor, completed after his death by Herbert M. Adler. Davis was also the father of Elsie and Nina Davis (Mrs. Redcliffe Salaman), who translated many of the difficult liturgical poems or piyyutim into non-literal verse. The genus of the idea for the Maḥzor was based on Solomon Schechter, had commented in one of his essays on the need for such an edition. Arthur Davis determined that it should be carried out with the greatest accuracy, both in the Hebrew text and the English version. He enjoyed the co-operation of his daughters and of Israel Zangwill who translated the poems in verse; and of another lay scholar, Herbert Adler, a lawyer nephew of the then Chief Rabbi Hermann Adler, for the prose translation.
