Category C: Chosen Ministers
Then David said, “No one may carry the ark of God but the Levites, for the LORD has chosen them to carry the ark of God and to minister before Him forever.” (1 Chronicles 15:2)
In this category, the clearly defined choice was the Levites, selected from among all the tribes of Israel. God selected them for the purpose and function of performing the ministry and service of the Lord in the Tabernacle. This choice was also permanent and not subject to change. Finally, the Levites were considered holy unto the Lord. As in the previous categories, so in this one we see all four elements present.
