The daily requirement for offerings commanded by Moses

2 Chronicles 8:12-18
New Moons and the three annual festivals—the Festival of Unleavened Bread, the Festival of Weeks and the Festival of Tabernacles. 除酵節、七七節、住棚節
In keeping with the ordinance of his father David, he appointed the divisions of the priests for their duties, and the Levites to lead the praise and to assist the priests according to each day’s requirement. He also appointed the gatekeepers by divisions for the various gates, because this was what David the man of God had ordered.
All Solomon’s work was carried out, from the day the foundation of the temple of the Lord was laid until its completion. So the temple of the Lord was finished.
And Hiram sent him ships commanded by his own men, sailors who knew the sea. These, with Solomon’s men, sailed to Ophir and brought back four hundred and fifty talents of gold, which they delivered to King Solomon.
Why?
All Solomon did for the Lord is obey the ordinance of his father David. If Solomon obeyed his fathers way will be great.
