Kabbalah zu Bereschit 1:29

The eleventh precept is to give a tithe of the land's product. Here we have two precepts. One is to give a tithe of the land's product, and the other is {to bring} the first fruits of the trees. As it is written, "Behold, I have given you every herb yielding seed, which is upon the face of all the earth" (Genesis 1:29). Here it is written, "I have given you;" elsewhere it is written, "And to the children of Levi, behold, I have given all the tithe in Yisrael" (Numbers 18:21). In a third place, it is further written, "And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is to Hashem" (Leviticus 27:30).

The twelfth precept - to bring the first fruits of the trees as an offering. As it is written, "and every tree, on which is the fruit of a tree yielding seed" (Genesis 1:29). Whatever I deserve is forbidden to you to eat. He permitted them (to eat) and gave them all His tithe and first fruits of the trees. "I have given to you" - "to you," and not to the generations after you.
