1 Kings 15:22
Then king Asa made a proclamation throughout all Judah; none was exempted: and they took away the stones of Ramah, and the timber thereof, wherewith Baasha had builded; and king Asa built with them Geba of Benjamin, and Mizpah. Then king Asa made a proclamation throughout all Judah; none was exempted: and they took away the stones of Ramah, and the timber thereof, wherewith Baasha had builded; and king Asa built with them Geba of Benjamin, and Mizpah.
The verse belongs to the history after 1 Kings 11 found in 1 Kings 12 to 22. That history traces the two separate kingdoms of Israel and Judah for about eighty years from the revolt of the ten tribes to the death of Jehoshaphat. It passes through the reigns of several kings of both kingdoms. Within that history the verse belongs to the reign of Asa in Judah following Abijah, also called Abijam. That reign was better than Abijam's reign and a time of prosperity for Judah.
Asa's reign occurred during the divided kingdom with two and a half tribes in Judah and ten tribes in Israel. There was war and strife between the divisions that could become open war. Asa was contemporary with Nadab, Baasha, Elah, Zimri, Omri and Ahab in Israel. The period of Asa's reign and the divided kingdom is an object lesson in the results of righteousness, backsliding, and sin.
The immediate context is Asa sending silver and gold to the king of Syria to persuade him to break his league with Baasha of Israel and help Asa against him. That silver and gold included the treasures of the Lord's house. The verse records that Asa proclaimed a mobilization throughout all Judah from which none was exempted. They took away the stones and timber with which Baasha had been building at Ramah and reused them to build Geba of Benjamin and Mizpah.
The division was followed by lasting financial weakness. After Egypt took the gold shields and Rehoboam replaced them with bronze shields, the kingdoms never regained their former financial strength before losing their independence.
