Genesis 2:15

This verse resumes the subject matter of Genesis 2:9, which has been interrupted by the description of the rivers.

to dress it and to keep it The Lord God puts man into the garden for a life, not of indolence, but of labour. "To dress it," that is to cultivate the soil, tend and prune the trees: "to keep it," that is to defend it from depredation by animals, or from the evils arising from unchecked luxuriance. In other words, he is given, from the first, his work to do by which he is (1) to improve his surroundings, (2) to provide for the necessities of life, (3) to protect from waste or loss that which is committed to his care. This work will exact abundant physical effort; it will exercise his powers of observation and judgement; it will furnish him with food for his body, and with thought for his mind.

Notice, that the garden requires to be dressed and kept; it is not a place of spontaneous perfection. Man in the garden is to work, to take trouble, to practise forethought, to exercise solicitude and sympathy for the objects of his toil. "Paradise" is not a place for indolence and self-indulgence.
