Acts 6 is very brief. In the past, my understanding was that these Greek-speaking widows were neglected, and the apostles were too busy to take care of them. The apostles said that the more important thing is to pay attention to the word of God (verse 2). There was no time to deal with these widows, but since they were protesting and making trouble, there was still a need for someone to deal with their need. Finally, Stephen and others were found. These people were not apostles, just ordinary disciples of Jesus who were spiritually mature due to it being the beginning of the apostolic era. Stephen was not only good at cooking, but also full of the Holy Spirit, faith, wisdom and the words of the Lord. Miracles also followed him and the other men who were serving. In short, the apostles did not have time to deal with these matters so they were handed over to others.
