Here again we may single out Capellus as a pioneer in criticism, in his Critica sacra sive de variis quae sacris V.
Capellus drew conclusions from such important facts as the occurrence of variations in the two Hebrew texts of passages found twice in the Old Testament itself, and the variations brought to light by a comparison of the Jewish and Samaritan texts of the Pentateuch, the Hebrew text and the Septuagint, the Hebrew text and New Testament quotations from the Old Testament.
In order that the principles already perceived by Capellus might be satisfactorily applied in establishing a critical text, many things were needed; for example, a complete collation of existing MSS.
More especially since the time of Capellus the value of the Septuagint for correcting the Hebrew text has been recognized; but it has often been used uncritically, and the correctness of the Hebrew text underlying it in comparison with the text of the Hebrew MSS., though still perhaps most generally underestimated, has certainly at times been exaggerated.
Conjectural emendations were offered by Capellus in the 17th, and by scholars such as C. F.
