'Fortifying' in the Bible

and he sendeth messengers unto Abimelech deceitfully, saying, 'Lo, Gaal son of Ebed and his brethren are coming into Shechem, and lo, they are fortifying the city against thee;

When Baasha learned of this, he stopped fortifying Ramah and remained in Tirzah,

so King Asa published a proclamation throughout Judah (no one was left out) and they carried away the stones and timber with which Baasha had been fortifying Judah. King Asa used them to fortify Geba in Benjamin and Mizpah.

When Baasha heard of it, he ceased fortifying Ramah and stopped his work.
