Hebrews 13:7 and Hebrews 13:17 are about the leaders of the church. In a time of persecution (as the Hebrews experienced), it is important to have leaders, who are guides, to lead the church through the difficulties. In Hebrews 13:7 the main task of a leader in the church is mentioned: speak the word of God (compare Acts 6:1–7). That is what the first leaders of the church did. They were called by Jesus. The apostles and elders who died, stayed faithful during difficult times. For example, think of the martyrdom of Stephen (Acts 6:1 – 8:40).
7 Souvenez-vous de vos conducteurs qui vous ont annoncé la parole de Dieu; considérez quelle a été la fin de leur vie, et imitez leur foi.
