To Work and Keep the Garden Means Torah and Offerings

Another interpretation of "to work it and to keep it": these refer to the sacrificial offerings, as it is said, "You shall serve God upon this mountain" (Exodus 3:12), and "You shall keep to offer to Me in its appointed time" (Numbers 28:2). "And He placed him in the Garden of Eden to work it." Lest you say there is labor in the Garden of Eden, such as breaking up and hoeing the soil, but do not all the trees grow on their own? Or lest you say there is labor in the Garden of Eden, such as watering the garden, but is it not written, "A river goes out from Eden to water the garden" (Genesis 2:10)? Rather, "to work it and to keep it" means to engage in the words of Torah and to keep its commandments, as it is said, "to keep the way of the tree of life" (Genesis 3:24), and as the verse says, "It is a tree of life to those who hold fast to it" (Proverbs 3:18).
