Hawker's Poor Man's Concordance And Dictionary

The Hebrews called the viper Peten, Ephee. It is frequently spoken of in Scripture, and not unfrequently in allusion to the great enemy of souls. (Job 20:16; Isaiah 30:6) And the Lord Jesus in the gospel called the children of the evil one a generation of vipers. (Matthew 12:34; Mat 23:33)
