The Lord is our God - We have not abandoned the Lord; and we still serve him according to his own law.

But as for us, the Lord is our God,.... The Word of the Lord, as the Targum; we know and acknowledge no other; not the calves at Dan and Bethel, nor any other idols, only the one living and true God:

and we have not forsaken him; his laws, statutes, ordinances, and worship; for though Abijah was not a religious man, yet it seems the form of religion was kept up, and temple service was observed, in his days:

and the priests which minister unto the Lord; by offering sacrifices, and burning incense:

are the sons of Aaron; and they only:

and the Levites wait upon their business; some in singing songs of praise, vocally and instrumentally, others in keeping the doors of the temple and the treasures of the house of God, and others in assisting the priests at the altar.

While, therefore, the Israelites have no-gods in their golden calves, Judah has Jahve for its God, whom it worships in His temple in the manner prescribed by Moses. "But in Jahve is our God, and we have not forsaken Him," in so far, viz., as they observed the legal Jahve-worship. So Abijah himself explains his words, "as priests serve Him the sons of Aaron (who were chosen by Jahve), and the Levites are בּמלאכת, in service," i.e., performing the service prescribed to them. As essential parts of that service of God, the offering of the daily burnt-offering and the daily incense-offering (Exodus 29:38., 2 Chronicles 30:7), the laying out of the shew-bread (Exodus 25:30; Leviticus 24:5.), the lighting of the lamps of the golden candlesticks (Exodus 25:37; Exodus 27:20.), are mentioned. In this respect they keep the יהוה משׁמרת (cf. Leviticus 8:35).

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:

13:10 The Lord - Heb. Jehovah, the only true God. We - Maintain his worship which you have rejected.

13:1-22 Abijah overcomes Jeroboam. - Jeroboam and his people, by apostacy and idolatry, merited the severe punishment Abijah was permitted to execute upon them. It appears from the character of Abijah, 1Ki 15:3, that he was not himself truly religious, yet he encouraged himself from the religion of his people. It is common for those that deny the power of godliness, to boast of the form of it. Many that have little religion themselves, value it in others. But it was true that there were numbers of pious worshippers in Judah, and that theirs was the more righteous cause. In their distress, when danger was on every side, which way should they look for deliverance unless upward? It is an unspeakable comfort, that our way thither is always open. They cried unto the Lord. Earnest prayer is crying. To the cry of prayer they added the shout of faith, and became more than conquerors. Jeroboam escaped the sword of Abijah, but God struck him; there is no escaping his sword.
