After that you shall come to the hill of God, where is the garrison of the Philistines: and it shall happen, when you are come there to the city, that you shall meet a band of prophets coming down from the high place with a psaltery, and a tambourine, and a pipe, and a harp, before them; and they will be prophesying:
A psaltery — נבל nebel. As the word signifies in other places a bottle or flagon, it was probably something like the utricularia tibia or BAG-PIPE. It often occurs both with the Greeks and Romans, and was evidently borrowed from the Hebrews.
