Charles Ellicott Commentary 2 Samuel 23:27

"Abiezer the Anathothite, Mebunnai the Hushathite," — 2 Samuel 23:27 (ASV)

Abiezer: He was general for the ninth month (1 Chronicles 27:12). He was of Anathoth, a priestly city of Benjamin, the home of Jeremiah.

Mebunnai: According to 2 Samuel 21:18 Sibbechai, and to 1 Chronicles 11:29 Sibbecai, these being the same in the Hebrew. The two names are much alike in the original and might be easily confused. He slew the giant Saph (2 Samuel 21:18), and was the general for the eighth month (1 Chronicles 27:11).
