In Nehemiah chapter 12 two references are made to “David the man of God”, in verses 24 and 36.
In verse 24 he is referred to as having commanded that praise and thanksgiving were made to God. In verse 36 certain musical instruments are attributed to him. These comments about David are references to things we read about in 1 Chronicles.
In 1 Chronicles 16 v. 4 we read about David appointing Levites to minister before the ark of God with thanks and praise to God. In chapter 23 v. 5 we read about 4000 Levites God directed him to appoint who praised the Lord with musical instruments that David said he had made for giving praise. And in verse 30 of the same chapter we read about the Levites he organised to thank and praise God every morning and evening.
From this we see the high priority David placed on thanking and praising God constantly and not just in one’s heart but outwardly. David made musical instruments specifically for this purpose.
In Nehemiah chapter 12 we are reminded that David was a man of God in connection with these things he did, commanding constant praise and thanks to God on instruments he made.
That tells us that one expression of godliness is the continual outward expression of thanks and praise to God.
