“And I saw what seemed to be a glassy sea mingled with fire, and those who come off victorious from the wild beast and from its image and from the number of its name standing by the glassy sea, having harps of God.”​—Revelation 15:2.

They have “harps of God,” and we therefore associate them with the 24 elders and the 144,000, since these groups also sing to a harp accompaniment. (Revelation 5:8; 14:2) The singers that John sees “come off victorious from the wild beast and from its image and from the number of its name.” So they must be those from among the 144,000 who live on earth during the last days. As a group, they do indeed come off victorious. For almost 90 years since 1919, they have refused to accept the mark of the wild beast or look to its image as man’s only hope for peace. Many of them have already endured faithful to the death, and these, now in heaven, doubtless follow with special delight the singing of their brothers who are still on earth.​—Revelation 14:11-13.

7. How was the harp used in ancient Israel, and how should the presence of harps of God in John’s vision affect us?

⁷ These loyal overcomers have harps of God. In this, they are like the temple Levites of old, who worshipped Jehovah with song to the accompaniment of harps. Some also prophesied to a harp accompaniment. (1 Chronicles 15:16; 25:1-3) The beautiful strains of the harp embellished Israel’s songs of joy and prayers of praise and thanksgiving to Jehovah. (1 Chronicles 13:8; Psalm 33:2; 43:4; 57:7, 8) In times of depression or captivity, the harp was not heard. (Psalm 137:2) The presence of harps of God in this vision should whet our anticipation for an exultant, triumphant song of praise and thanksgiving to our God.a
