'Harp' in the Bible

And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?

When He took the scroll, the four living creatures and the 24 elders fell down before the Lamb. Each one had a harp and gold bowls filled with incense, which are the prayers of the saints.

No harp or song, no flute or trumpet, shall ever again be heard in thee; no craftsman of any kind shall ever again be found in thee; nor shall the grinding of the mill ever again be heard in thee.
