Hippolytus, On the Psalms (attributed) 1
The Book of Psalms contains new teaching that comes after Joshua's legislation. In fact, it counts as the second instructional book after Joshua's writing. After Moses and Joshua died, David arose after the period of the judges. He was deemed worthy to be called the father of the Savior, and he first handed down to the Hebrews a new way of singing psalms. Through this way he abolishes the sacrificial regulations that Moses legislated, and he introduces a new way of worshiping God through hymns and shouts. He also teaches many other things that repeat the law of Joshua, drawing from the material of his own work.

Ἡ βίβλος τῶν ψαλμῶν καινὴν διδασκαλίαν περιέχει, μετὰ τὴν ΔἋΙωσέως νομοϑεσίαν, καὶ ὅτε δευτέρα μετὰ τὴν Διωσέως γραφὴν διδωσχαλιχὴ βίβλος τυγχάνει. μετὰ γοῦν τὴν Μωσέος κεὰὶ Ἰησοῦ τελευὃ τὴν καὶ μετὰ τοὺς κριτὰς Δαυὶδ γενόμενος, ὡσανεὶ τοῦ σωτῆρος αὐτὸς χρηματίσαι πατὴρ καταξιωϑείς, καινὸν τρόπον τὸν τῆς ψαλμῳδίας πρῶτος Ἑβραίοις παρέδωκεν, δι ἣς ἀναιρεῖ μὲν τὰ παρὰ Μωσῇ περὶ ϑυσιῶν νενομοϑετημένα, καινὸν δὲ τὸν δι ὕμνων καὶ ἀλαλαγμῶν τρόπον τῆς τοῦ ϑεοῦ λατρείας εἰσάγει καὶ ἄλλα δὲ πλεῖστα τὸν ίωσέως νόμον ἐπαναβεβηκότα δ ὕλης αὐτοῦ τῆς πραγματείας διδάσκει.
