Cf. Phil. Jud. de Plantatione Noë, II § 33:  “And his name was called Judah, which being interpreted is “confession to the Lord.”  In Gen. xlix. 8 the name is differently interpreted:  “Judah, thou art he whom thy brethren shall praise.”  The root has both senses “to confess,” and “to praise,” which are closely allied since to “confess” is to “give God the glory” (Josh. vii. 19).
