‏ Psalms 98:1

Greeting to Him Who Is Become Known in Righteousness and Salvation

This is the only Psalm which is inscribed מזמור without further addition, whence it is called in B. Aboda Zara, 24 b, מזמורא יתומא (the orphan Psalm). The Peshîto Syriac inscribes it De redemtione populi ex Aegypto; the “new song,” however, is not the song of Moses, but the counterpart of this, cf. Rev 15:3. There “the Lord reigneth” resounded for the first time, at the sea; here the completion of the beginning there commenced is sung, viz., the final glory of the divine kingdom, which through judgment breaks through to its full reality. The beginning and end are taken from Psa 96:1-13. Almost all that lies between is taken from the second part of Isaiah. This book of consolation for the exiles is become as it were a Castalian spring for the religious lyric.
