1 CHRONICLES 25
1 Moreover David and the captains of the host separated to the service of the sons of Asaph, and of Heman, and of Jeduthun, who should prophesy with harps, with psalteries, and with cymbals: and the number of the workmen according to their service was:
The Temple Psalmody
-"In the employment of psalmody in the public worship of the Temple, David established a choir of 4,000 singers and musicians, over which he placed 288 skilled musicians and 'masters of song.' These he divided into twenty-four courses, twelve in each course, to take the services in rotation.
There were three accomplished leaders or 'choir-masters' chosen from the three Levite families-Heman of the Kohathites, Asaph of the Gershonites, and Jeduthun (Etham) of the Merarites. They were musical teachers, prophets, and seers" (1 Chron. 25:1-7).

The Christadelphian, Apr 1888
7 So the number of them, with their brethren that were instructed in the songs [shir] of Yahweh, even all that were cunning [skilled], was 288.
But besides the twenty-four orders of Aaron's sons, there were, in the ecclesiastical department of David's kingdom, twenty-four orders of Levites, sons of Asaph, Heman, and Jeduthun, whom he separated for the temple service, "to prophesy with harps, with psalteries, and with cymbals, to give thanks and to praise Yahweh Tz'vaoth."
The number of those "who were instructed in the songs of Yahweh," were two hundred and eighty-eight, and were divided into twenty-four companies of twelve each, "as well the small as the great, the teacher as the scholar" being reckoned in each twelve (1 Chron. xxv. 1,3,7).
These were also typical of those symbolized by the twenty-four elders who were represented to John in (Apoc) ch. v. 8, as "having each one harps and golden censers full of incense, which are the prayers of the saints; and they sang a new song."
There are twenty-four symbolical elders because the sons of the High Priest and the singers who did the service of the temple under David's reign were twenty-four orders each; and in the aggregate typified the saints, the Elohim of Israel, who shall perform the temple service of the restored kingdom of David, when David's Son, the "Greater than Solomon," shall be High Priest of the kingdom after the Order of Melchizedec.
The twenty-four elders represent both the priests and singers of the Ezekiel Temple which is to be built by "the man whose name is The Branch" (Zech. vi. 12,15). There will be twenty-four orders "as in the days of old" (Amos ix. 11); who will be "the harpers harping with their harps, and singing a new song" (Apoc. xiv. 2,3); even "the song of Moses, the servant of God, and the song of the Lamb" (xv. 2-4).
