"U'shnei na'arav ito." The pshat - straightforward translation of this is that he (Avraham) had his two young men with him, assisting. On a sod/drash - deep homiletical level it can mean that he had the years of his youth with him. Though Avraham was advanced in his years he brought youthful enthusiasm to his service of G-d. - The Sabba Kadosh of Slonim, Torat Avot
