'Harp' in the Bible

And when He had taken the book, the four living creatures and the twenty-four Elders fell down before the Lamb, having each of them a harp and bringing golden bowls full of incense, which represent the prayers of God's people.

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.
