At the end of three months he resolved to make another attempt to remove the ark, and he now gave earnest heed to carry out in every particular the directions of the Lord. Again the chief men of the nation were summoned, and a vast assemblage gathered about the dwelling place of the Gittite. With reverent care the ark was now placed upon the shoulders of men of divine appointment, the multitude fell into line, and with trembling hearts the vast procession again set forth. After advancing six paces the trumpet sounded a halt. By David's direction sacrifices of “oxen and fatlings” were to be offered. Rejoicing now took the place of trembling and terror. The king had laid aside his royal robes and had attired himself in a plain linen ephod, such as was worn by the priests. He did not by this act signify that he assumed priestly functions, for the ephod was sometimes worn by others besides the priests. But in this holy service he would take his place as, before God, on an equality with his…
The EGW passage directly illustrates the principle stated in 1 Chronicles 15:13: that seeking God 'after the due order' is essential. David's initial failure and subsequent correction demonstrate this principle.
1 Chronicles 15:16"And David spake to the chief of the Levites to appoint their brethren to be the singers with instruments of musick, psalteries and harps and cymbals, sounding, by lifting up the voice with joy."
"In bringing to the temple the sacred ark containing the two tables of stone on which were written by the finger of God the precepts of the Decalogue, Solomon had followed the example of his father David. Every six paces he sacrificed. With singing and with music and with great ceremony, “the priests brought in the ark of the covenant of the Lord unto his place, to the oracle of the house, into the most holy place.” Verse 7 . As they came out of the inner sanctuary, they took the positions assigned them. The singers—Levites arrayed in white linen, having cymbals and psalteries and harps—stood at the east end of the altar, and with them a hundred and twenty priests sounding with trumpets. See Verse 12 . PK 38.2"
The EGW passage describes the Levites as singers with instruments of music, psalteries, harps, and cymbals, which is directly alluded to in 1 Chronicles 15:16.
"A band of singers and players answered: PP 707.5"
Both passages refer to singers and musicians being appointed. EGW's passage is a very brief reference to the broader event described in 1 Chronicles 15:16.
1 Chronicles 15:29"And it came to pass, as the ark of the covenant of the Lord came to the city of David, that Michal the daughter of Saul looking out at a window saw king David dancing and playing: and she despised him in her heart."
"Again the long train was in motion, and the music of harp and cornet, trumpet and cymbal, floated heavenward, blended with the melody of many voices. “And David danced before the Lord,” in his gladness keeping time to the measure of the song. PP 707.1"
Both passages describe David dancing before the Lord in connection with the Ark of the Covenant. While the EGW passage focuses on the joyful music and dancing, 1 Chronicles 15:29 provides a different perspective through Michal's reaction. The common theme is David's dancing in relation to the Ark.
