John Gill's Bible Commentary Ver. 6. And there was war between Rehoboam and Jeroboam all the days of his life .] Not the days of Rehoboam, though that was true, and is observed, ( 1 Kings 14:30), but all the days of Abijam, before he came to the throne, and in which, when a young man, he was concerned, and which still continued between him and Jeroboam; though some think he is called by his father’s name, as Rehoboam is called David, ( 1 Kings 12:16).
Matthew Henry Commentary
Verses 1-8 - Abijam's heart was not perfect with the Lord his God; he wante sincerity; he began well, but he fell off, and walked in all the sin of his father, following his bad example, though he had seen the ba consequences of it. David's family was continued as a lamp in Jerusalem, to maintain the true worship of God there, when the light of Divine truth was extinguished in all other places. The Lord has stil taken care of his cause, while those who ought to have been serviceabl thereto have lived and perished in their sins. The Son of David wil still continue a light to his church, to establish it in truth an righteousness to the end of time. There are two kinds of fulfilling the law, one legal, the other by the gospel. Legal is, when men do all things required in the law, and that by themselves. None ever thu fulfilled the law but Christ, and Adam before his fall. The gospe manner of fulfilling the law is, to believe in Christ who fulfilled the law for us, and to endeavour in the whole man to obey God in all his precepts. And this is accepted of God, as to all those that are in Christ. Thus David and others are said to fulfil the law.
