Leviticus 19:23

As uncircumcised — That is, As unclean, not to be eaten but cast away. This precept was serviceable, To the trees themselves, which grew the better and faster, being early stript of those fruits, which otherwise would have drawn away much more of the strength from the tree. To men, both because the fruit then was less wholesome, and because hereby men were taught to bridle their appetites; a lesson of great use and absolute necessity in a holy life.
