Chapter LVII.
Trypho, pupil of Origen, to whom some of his extant letters are addressed, was very learned in the Scriptures, and this many of his works show here and there, but especially the book which he composed On the red heiferin Deuteronomy, and On the halves, which with the pigeon and the turtledoves were offered by Abraham as recorded in Genesis.
