2 Chronicles 11:22

And Rehoboam made Abijah the son of Maachah... brethren. — Rather, And Rehoboam appointed Abijah the son of Maachah for head — to wit, for prince (nagîd) — among his brethren. The expression “head” is explained by the following clause.

For he thought to make him king. — This gives the sense of the brief Hebrew phrase, “for — for making him king.” In making Abijah heir to the throne, it does not appear that Rehoboam infringed the law of Deuteronomy 21:15, as the Speaker’s Commentary suggests. The right of the firstborn was only a double share of a man’s property. (Comp. 1 Kings 1:35 for a precedent.)
