Psalm 150:4 , a wind instrument apparently composed of several pipes. It cannot, however, mean the modern organ, which was unknown to the ancients; but refers probably to the ancient syrinx, or pipes, similar to the Pandean pipes, a series of seven or more tubes of unequal length and size, closed at one end, and blown into with the mouth at the other, Genesis 4:21 Job 21:12 .
