king of Egypt, the Sheshonk I of the monuments, first sovereign of the Bubastite twenty-second dynasty. His reign offers the first determined syncronism of Egyptian and Hebrew history. The first year of Shishak would about correspond to the 26th of Solomon, and the 20th of Shishak to the 5th of Rehoboam. Shishak at the beginning of his reign received the fugitive Jeroboam (1 Kings 11:40), and it was probably at the instigation of Jeroboam that he attacked Rehoboam. “He took the fenced cities which [pertained] to Judah, and came to Jerusalem.” He exacted all the treasures of his city from Rehoboam and apparently made him tributary (1 Kings 14:25-26; 2 Chronicles 12:2-9). Shishak has left a record of this expedition sculptured on the wall of the great temple of El-Karnak. It is a list of the countries, cities and tribes conquered or ruled by him, or tributary to him.
