Adjective argos (unproductive) in the Gospels-Acts

(Translation from NRSV with a few modifications for a more literal meaning)


Matthew

12: 36I tell you, on the day of judgment you will have to give an account for every unproductive (argos) word you utter;
20: 3When he went out about nine o'clock, he saw others standing unproductive (argos) in the marketplace;
20: 6And about five o'clock he went out and found others standing around; and he said to them, 'Why are you standing here unproductive (argos) all day?'
