Ps 98:1
98:1 <> O sing {a} unto the LORD a new song; for he
     hath done marvellous things: his right hand, and his holy
     {b} arm, hath gotten him the victory.

     (a) That is, some song newly made in token of their
         wonderful deliverance by Christ.
     (b) He preserves his Church miraculously.

Ps 98:2
98:2 The LORD hath made known his {c} salvation: his
     righteousness hath he openly shewed in the sight of the
     heathen.

     (c) For the deliverance of his Church.

Ps 98:3
98:3 He hath {d} remembered his mercy and his truth toward the
     house of Israel: all the ends of the earth have seen the
     salvation of our God.

     (d) God was moved by no other means to gather his Church
         from the Jews and Gentiles, but because he would
         perform his promise.

Ps 98:6
98:6 With {e} trumpets and sound of cornet make a joyful noise
     before the LORD, the King.

     (e) By this repetition and earnest exhortation to give
         praise with instruments, and also of the dumb
         creatures, he signifies that the world is never able to
         praise God sufficiently for their deliverance.
