Hellenists were Jews who adopted the Greek language and culture. They issued a complaint that there widows were not recieving proper nourishment. The apostles had to focus on the commission applied to them, so Stephen was chosen to overlook the distribution of food, to make sure none were being neglected. Stephen was faithful, and pleased to do this work for the Lord. Stephen was full of the Spirit, and spoke as such, presenting the Lord to the people. This angered the council again, who seized him, and brought him to trial. A false witness breaks a command of God. False witnesses were called against Jesus, and they were used against Stephen. Stephen had the face of an angel, the truth was emitting through him. Luke, who wrote Acts, speaks of Stephen as if he knew him personally, which he may have.
