Chapter 12

12:6  Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan: and there fell at that time of the Ephraimites forty and two thousand.

Shibboleth

Signifying a stream or flood.

12:8  And after him Ibzan of Bethlehem judged Israel.

Ibzan

He seems to have been only a civil judge in northeast Israel.
