I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you know the Father.
I write unto you, young men - νεανίσκοι neaniskoi. This word would properly embrace those who were in the vigor of life, midway between children and old men. It is uniformly rendered “young men” in the New Testament: Matthew 19:20, Matthew 19:22; Mark 14:51; Mark 16:5; Luke 7:14; Acts 2:17; Acts 5:10; and in the passages before us. It does not elsewhere occur. It is commonly understood as embracing those in the prime and vigor of manhood up to the period of about forty years. - Robinson.
