"At last the temple planned by King David, and built by Solomon his son, was completed. “All that came into Solomon's heart to make in the house of the Lord,” he had “prosperously effected.” 2 Chronicles 7:11 . And now, in order that the palace crowning the heights of Mount Moriah might indeed be, as David had so much desired, a dwelling place “not for man, but for the Lord God” ( 1 Chronicles 29:1 ), there remained the solemn ceremony of formally dedicating it to Jehovah and His worship. PK 37.1"
"Thus Solomon finished the house of the Lord, and the king’s house: and all that came into Solomon’s heart to make in the house of the Lord, and in his own house, he prosperously effected."
Ellen White directly references 2 Chronicles 7:11 in this passage.
"Furthermore David the king said unto all the congregation, Solomon my son, whom alone God hath chosen, is yet young and tender, and the work is great: for the palace is not for man, but for the Lord God."
Ellen White directly references 1 Chronicles 29:1 in this passage.
"The time chosen for the dedication was a most favorable one—the seventh month, when the people from every part of the kingdom were accustomed to assemble at Jerusalem to celebrate the Feast of Tabernacles. This feast was preeminently an occasion of rejoicing. The labors of the harvest being ended and the toils of the new year not yet begun, the people were free from care and could give themselves up to the sacred, joyous influences of the hour. PK 37.3"
"Speak unto the children of Israel, saying, The fifteenth day of this seventh month shall be the feast of tabernacles for seven days unto the Lord."
EGW describes the Feast of Tabernacles, referencing the time of year and its significance, which is based on the commandment in Leviticus 23:34.
