1 Kings 15:17

Ramah (perhaps “Er-Ram;” marginal reference) was situated halfway between Bethel and Jerusalem. Its distance from Jerusalem was no more than five miles so that its occupation was a menace to that capital. Baasha’s seizure of Ramah implies a previous recovery of the towns taken by Abijam from Jeroboam, namely, Bethel, Jeshanah, and Ephrain 2 Chronicles 13:19, and was a carrying of the war into the enemy’s country. Could his conquest have been maintained, it would have crippled Judah seriously, and have almost compelled a transfer of the capital to Hebron.

That he might not suffer any to go out or come in - Baasha, in seizing Ramah, professed to be acting on the defensive. His complaint seems to have been well founded (compare 2 Chronicles 15:9); but it was more than a defensive measure - it was the first step toward a conquest of the southern kingdom.
