Psalms 150:3

Praise him with the sound of the trumpet,.... Which was used in calling the assembly together, for worship and on other occasions; and at the feast of blowing of trumpets, and in the year of jubilee,

Numbers 10:1; and by the priests in temple service,

1 Chronicles 16:6; and was typical of the Gospel, which gives a certain and joyful sound, and is the cause and means of praising God, Isaiah 27:13;

praise him with the psaltery; to which psalms were sung;

and harp; which were instruments of music, both used in divine worship under the former dispensation; and in which David was well skilled and delighted, and appointed proper persons to praise with them,

1 Chronicles 15:20. They were typical of the spiritual melody made in the hearts of God's people, while they are praising him in psalms, hymns, and spiritual songs, under the Gospel, Ephesians 5:19.
