2 Chronicles 13:4

4. Stood up upon mount Zemaraim A general standing upon an eminence, could, like Jotham on Mount Gerizim, speak so as to be heard by a vast audience below. See note on Judges 9:7. The locality of Mount Zemaraim is uncertain. Some have thought to connect it with the Benjamite town of the same name mentioned in Joshua 18:22. But that was in the Jordan valley, this in Mount Ephraim. It was probably an eminence near the border of the two kingdoms, perhaps not far from Beth-el, near which the great battle was fought.

Hear me, thou Jeroboam Abijah vainly thinks to make his enemies see the sin and folly of their separating from the kingdom of David. His speech was one sided, for he failed to observe that the permanency and integrity of David’s kingdom were conditioned upon obedience.
