To swell up, to burn, to become inflated. Used in Acts 28:6 when the Maltese expected Paul to swell up after being bitten by a viper.
After Paul was bitten by a viper on Malta, the islanders watched, expecting him to swell up and die (Acts 28:6). When nothing happened, they changed their minds about him. God's protection of His servants confounds human expectations. The viper could not harm the one God was determined to deliver to Rome.
