Shishak (shî-shăk). King of Egypt, known as Sheshonk I. The first year of Shishak would about correspond to the 26th of Solomon, b.c. 989, 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.
