shib.bol denotes a stream in Isaiah and appears as the spoken test word “Shibboleth” in Judges.

The clearest attested use identifies a stream in a boundary-like clause in Isaiah 27:12; Judges 12:6 instead presents the word as the pronunciation demanded in a test. The APB does not isolate a corresponding English expression for the forms in Psalm 69:16 and Psalm 69:3.
