(Note: The reading διὰ Ἠσαΐ́ου τοῦ προφήτου is, although erroneous, nevertheless ancient; since even the Clementine Homilies introduce this passage as the language of Isaiah.)

He here recounts to the people their history מנּי־קדם, from that Egyptaeo-Sinaitic age of yore to which Israel's national independence and specific position in relation to the rest of the world goes back. It is not, however, with the external aspect of the history that he has to do, but with its internal teachings. משׁל is an allegory or parable, παραβολή, more particularly the apophthegm as the characteristic species of poetry belonging to the Chokma, and then in general a discourse of an elevated style, full of figures, thoughtful, pithy, and rounded. חידה is that which is entangled, knotted, involved, perlexe dictum. The poet, however, does not mean to say that he will literally discourse gnomic sentences and propound riddles, but that he will set forth the history of the fathers after the manner of a parable and riddle, so that it may become as a parable, i.e., a didactic history, and its events as marks of interrogation and nota-bene's to the present age. The lxx renders thus: ἀνοίξω ἐν παραβολαῖς τὸ στόμα μου, φθέγξομαι προβλήματα ἀπ ̓ ἀρχῆς. Instead of this the Gospel by Matthew has: ἀνοίξω ἐν παραβολαῖς τὸ στόμα μου, ἐρεύξομαι κεκρυμμένα ἀπὸ καταβολῆς (κόσμου), and recognises in this language of the Psalm a prophecy of Christ; because it is moulded so appropriately for the mouth of Him who is the Fulfiller not only of the Law and of Prophecy, but also of the vocation of the prophet. It is the object-clause to נכחד, and not a relative clause belonging to the "riddles out of the age of yore," that follows in Psalm 78:3 with אשׁר, for that which has been heard only becomes riddles by the appropriation and turn the poet gives to it. Psalm 78:3 begins a new period (cf. Psalm 69:27; Jeremiah 14:1, and frequently): What we have heard, and in consequence thereof known, and what our fathers have told us (word for word, like Psalm 44:1; Judges 6:13), that will we not hide from their children (cf. Job 15:18). The accentuation is perfectly correct. The Rebı̂a by מבניהם has a greater distinctive force than the Rebı̂a by אחרון (לדור); it is therefore to be rendered: telling to the later generation (which is just what is intended by the offspring of the fathers) the glorious deeds of Jahve, etc. The fut. consec. ויּקם joins on to אשׁר עשׂה. Glorious deeds, proofs of power, miracles hath He wrought, and in connection therewith set up an admonition in Jacob, and laid down an order in Israel, which He commanded our fathers, viz., to propagate by tradition the remembrance of those mighty deeds (Exodus 13:8, Exodus 13:14; Deuteronomy 4:9, and other passages). להודיעם has the same object as והודעתּם in Deuteronomy 4:9; Joshua 4:22. The matter in question is not the giving of the Law in general, as the purpose of which, the keeping of the laws, ought then to have been mentioned before anything else, but a precept, the purpose of which was the further proclamation of the magnalia Dei, and indirectly the promotion of trust in god and fidelity to the Law; cf. Psalm 81:5., where the special precept concerning the celebration of the Feast of the Passover is described as a עדוּת laid down in Joseph. The following generation, the children, which shall be born in the course of the ages, were to know concerning His deeds, and also themselves to rise up (יקוּמוּ, not: come into being, like the יבאוּ of the older model-passage Psalm 22:32) and to tell them further to their children, in order that these might place their confidence in god (שׂים כּסל, like שׁית מחסה in Psalm 73:28), and might not forget the mighty deeds of God (Psalm 118:17), and might keep His commandments, being warned by the disobedience of the fathers. The generation of the latter is called סורר וּמרה, just as the degenerate son that is to be stoned is called in Deuteronomy 21:18. הכין לבּו, to direct one's heart, i.e., to give it the right direction or tendency, to put it into the right state, is to be understood after Psalm 78:37, 2 Chronicles 20:33, Sir. 2:17.
