2 Chronicles 13:10
But as for us, the LORD is our God, and we have not forsaken him; and the priests, which minister unto the LORD, are the sons of Aaron, and the Levites wait upon their business: But as for us, the LORD is our God, and we have not forsaken him; and the priests, which minister unto the LORD, are the sons of Aaron, and the Levites wait upon their business:
The verse belongs to the account of Abijah's reign and the war between Judah and Israel against Jeroboam in the time of Rehoboam and Abijah, which ended in Judah's victory with the conquest of its enemy and in Israel's defeat. In that setting it stands within Abijah's appeal to Israel, in which he invoked God's covenant with David and warned Israel against fighting against God, as a reminder that the covenant remained in force, and Israel's defeat followed the battle.
The verse states Judah's professed loyalty and rightful worship in contrast to Israel in the divided kingdom, that the LORD was its God whom it had not forsaken, with Aaron's descendants as ministering priests and the Levites attending to their appointed work. It describes the temple's daily service as continuing the priestly service prescribed for the tabernacle, with priests ministering daily in the Holy Place and at the altar and incense burned when the lamps were tended each morning and evening. Judah's professed loyalty and rightful worship in contrast to Israel provides a historical parallel to the North and the South during the American Civil War.
