Ministry of Aaron and the Levites

1 Chronicles 6:49-81
    49 But Aaron and his sons offered sacrifices on the altar of burnt offering and on the altar of incense, for all the work of the Most Holy Place, and to make atonement for Israel, according to all that Moses the servant of God had commanded. 50 Now these are the sons of Aaron: Eleazar his son, Phinehas his son, Abishua his son, 51 Bukki his son, Uzzi his son, Zerahiah his son, 52 Meraioth his son, Amariah his son, Ahitub his son, 53 Zadok his son, and Ahimaaz his son.
    54 Now these are their dwelling places throughout their settlements in their territory, for they were given by lot to the sons of Aaron, of the family of the Kohathites: 55 They gave them Hebron in the land of Judah, with its surrounding common-lands. 56 But the fields of the city and its villages they gave to Caleb the son of Jephunneh. 57 And to the sons of Aaron they gave one of the cities of refuge, Hebron; also Libnah with its common-lands, Jattir, Eshtemoa with its common-lands, 58 Hilen with its common-lands, Debir with its common-lands, 59 Ashan with its common-lands, and Beth Shemesh with its common-lands. 60 And from the tribe of Benjamin: Geba with its common-lands, Alemeth with its common-lands, and Anathoth with its common-lands. All their cities among their families were thirteen.
    61 To the rest of the family of the tribe of the Kohathites they gave by lot ten cities from half the tribe of Manasseh. 62 And to the sons of Gershon, throughout their families, they gave thirteen cities from the tribe of Issachar, from the tribe of Asher, from the tribe of Naphtali, and from the tribe of Manasseh in Bashan. 63 To the sons of Merari, throughout their families, they gave twelve cities from the tribe of Reuben, from the tribe of Gad, and from the tribe of Zebulun. 64 So the children of Israel gave these cities with their common-lands to the Levites. 65 And they gave by lot from the tribe of the children of Judah, from the tribe of the children of Simeon, and from the tribe of the children of Benjamin these cities which are called by their names.
    66 Now some of the families of the sons of Kohath were given cities as their territory from the tribe of Ephraim. 67 And they gave them one of the cities of refuge, Shechem with its common-lands, in the mountains of Ephraim, also Gezer with its common-lands, 68 Jokmeam with its common-lands, Beth Horon with its common-lands, 69 Aijalon with its common-lands, and Gath Rimmon with its common-lands. 70 And from the half-tribe of Manasseh: Aner with its common-lands and Bileam with its common-lands, for the rest of the family of the sons of Kohath.
    71 From the family of the half-tribe of Manasseh the sons of Gershon were given Golan in Bashan with its common-lands and Ashtaroth with its common-lands. 72 And from the tribe of Issachar: Kedesh with its common-lands, Daberath with its common-lands, 73 Ramoth with its common-lands, and Anem with its common-lands. 74 And from the tribe of Asher: Mashal with its common-lands, Abdon with its common-lands, 75 Hukok with its common-lands, and Rehob with its common-lands. 76 And from the tribe of Naphtali: Kedesh in Galilee with its common-lands, Hammon with its common-lands, and Kirjathaim with its common-lands.
    77 From the tribe of Zebulun the rest of the children of Merari were given Rimmon with its common-lands and Tabor with its common-lands. 78 And on the other side of the Jordan, across from Jericho, on the east side of the Jordan, they were given from the tribe of Reuben: Bezer in the wilderness with its common-lands, Jahzah with its common-lands, 79 Kedemoth with its common-lands, and Mephaath with its common-lands. 80 And from the tribe of Gad: Ramoth in Gilead with its common-lands, Mahanaim with its common-lands, 81 Heshbon with its common-lands, and Jazer with its common-lands.

Aaron and the Levites are mentioned here in depth genealogically.  The three tasks given them by God through Moses were to offer sacrifices, do work in the holy of holies, and to make atonement for all Israel.  This means that they were intercessors to atone for the sin of the people by required sacrifices and they were to attend to the place of ultimate worship to the LORD in maintaining themselves and the Holy of Holies where the high priest communed with God.  All the lands given the descendants are also carefully laid out for us to consider God’s grace and care for those serving Him, reminding us of Paul testifying that those who labor in God’s word and work in the fulfillment of the Law (which is the gospel of grace) should live by that work and be taken care of (1 Corinthians 9:13-14) by God’s people.  Though we are all priests to our God, some He has set apart for specific ministries and should be supported by the congregation as the pattern of the die was cast here.  This means they must also serve the Lord Christ and intercede for the congregation in word and deed.  This passage also deals with land given permanently to the priests.  The land given to the Levites has echoed to the laws of the land giving tax free status to church buildings in a sense like the Levites and their devoted lands given permanently to them.  Of course we do not live in a theocracy and the government is not of God nor conscious of His rule and therefore not under compulsion to take care of God’s servants like this, but it is of note that those creating such laws were cognizant of this responsibility.  We see then the patterns of ministry here with Aaron and the Levites.
