Robertson's Word Pictures (NT)
With jealousy (zhlou). Genitive case. Old word from ze", to boil, our zeal. In itself it means only warmth, ardour, zeal, but for a bad cause or from a bad motive, jealousy, envy, rivalry results (Acts 13:45). Common in the epistles.
In public ward (en thrhsei dhmosiai). As in Acts 4:3 only with dhmosiai (public) added, in the public prison, perhaps not the "common" prison, but any prison is bad enough. In verse Acts 5:19 it is called "the prison" (thv fulakhv), the guardhouse.
