The consecration or the dedication of the wall surely means the rededication and consecration of the entire city. The temple of course had been rebuilt some years previously, and now the walls have been rebuilt and we read about how the city began to be more properly inhabited, and the leaders were coming back into the city.
You think of the sad thing that happened in church history to the Lutheran Church in Germany in the decades and the centuries following the Reformation. It began with such soundness and such clarity in its confessional standards. Yes, there were problems of course from our Baptist point of view, but nevertheless, it began as a gospel denomination. And yet, because high culture came in and music became so important – and in their case, music of a worshipful standard; not the kind of worldly music that evangelical churches seem to swerve towards today – it pretty well wrecked the Lutheran Church. The beauty of very sophisticated worship became more important than the content of the worship to so many people. Under God's arrangements for the Old Testament people that was never supposed to happen. So there were very considerable restrictions. Generally speaking, only stringed instruments were ever allowed to accompany sung worship either at home or in synagogues, but certainly in the temple. There was no loud percussion accompanying the worship in ancient times, even when they were rejoicing.
When it comes to any discussion on worship, there is a tremendous lightness with some of the evangelical leaders on this subject. They all say the same type of things. They say, ‘Ah, what we do is no different from Psalm 150’, and in their view Psalm 150 permits all kinds of instrumentation in the Christian church today. Why, is not Christ the same yesterday, today, and forever? And they could have every instrument under the sun in those days. But Psalm 150 cannot possibly be describing the instrumentation of temple worship, because if it were, the Bible would contradict itself. The rules in 1 and 2 Chronicles, laid down by inspiration of the Spirit and given to David are still being scrupulously observed wherever there was reform, 550 years later, as in this Book of Nehemiah. Those rules forbad any but four specified instruments in the temple. So Psalm 150 is not describing literal temple worship. There are three other psalms that mention instruments that are not prescribed for temple worship. In the case of the other three psalms, it is very obvious that they are not describing temple worship, but open-air thanksgiving festivities. Israel was a nation as well as a state, and because they were a nation they had open-air events: greater victory parades for battles in which God gave victory, when the little girls would dance in front of the procession with their tambourines, which were never allowed in the temple. So Psalm 150 is referring either to outdoor festivities – all forms of worship under the firmament, under heaven, not the direct worship of God according to his prescription in the temple – or else it's a highly figurative psalm, and it’s using the different instruments to suggest moods and tones for praise. The one thing it isn't, is a literal description of Old Testament praise.
