Kabbalah su Esodo 24:5

The benefit of one who is cautious about emitting semen in vain was explained in Tana Devei Eliyahu in the portion of Mishpatim, in the verse “And he sent the young men of Israel who offered burnt-offerings” (Exodus 24:5), and this is what is says: “We learned in the school of Eliyahu about the verse “There is no one like God, O Yeshurun” (Deuteronomy 33:26), happy is the man who has words of Torah with him and that semen did not come out from him in vain. And even if he is an Israelite he is fit to give sacrifices on the altar like the High Priest, as it says “And he sent the young men of Israel” (Exodus 24:5). Whoever makes himself lazy to commit a sin and does not do it, he is nurtured from the radiance of the Shechinah, as it says “and they looked upon God, they ate and drank” (Exodus 24:11).”
