Over a dozen reasons why the argument for Exclusive Psalmody doesn't stand up, Part 16

16. A number of the Psalms could not have been sung in public worship as they contained instructions forbidden in public worship. 

The Lord laid down strict instructions as to what musical instruments were to be employed in public worship in the Temple. These instructions relate to four musical instruments, namely: the trumpet, harp, psaltery and cymbals.

The use of the trumpet was present from the very beginning of the Mosaic economy. The silver trumpets were to be blown at set times, cf. Numbers 10:2-.

15. Singing Psalms which make mention of musical instruments

It would be very insteresting to know whether exclusive Psalmist sing all the 150 psalms of the Psalter? This question is asked in the light of the numerous places in the Psalter where mention is made of singing accompanied by musical instrument, either in the title, which is part of the inspired record or in the Psalm itself.

The metrical version of the Psalms omits the inclusion of the inspired titles of the Psalms and yet makes the claim that the metrical version is a faithful translation of the original. How can the metrical version be described as a faithful translation when it omits the inspired titles of many of the Psalms? In many cases where an inspired title is given to the Psalm it forms verse 1. There is actually one verse more in the Hebrew Bible than in the Authorised Version or the metrical version. At least the Authorised Version includes the title separately, whereas the metrical version omits it altogether!

Would this omisison have anything to do with the fact that in a number of these inspired titles there are specific commands given to sing the Psalm with the accompaniment of musical instruments?
