2:15And the LORD God took the man, and put him into the garden of Eden to dress it and to keep it.

4:2And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

4:3And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD.

4:12When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth.
