Of the sons of Asaph
Who were separated, and by lot appointed, to the service of singers in the temple:
Zaccur, and Joseph, and Nethaniah, and Asarelah;
called Jesharelah, ( 1 Chronicles 25:14 ) , these had the third fourth, fifth, and seventh lots, ( 1 Chronicles 25:9 1 Chronicles 25:10 1 Chronicles 25:12 1 Chronicles 25:14 ) ,
under the hands of Asaph;
under his instruction and authority:
which prophesied according to the order of the king;
which Asaph composed psalms under the inspiration of the Spirit of God, and was ordered by King David to sing them, and by whose command they were inserted in the book of Psalms, where they now stand with his name to them.
