Genesis 2:5-6, 9

there were still no plants on the earth. Nothing was growing in the fields because the LORD God had not yet made it rain on the land. And there was no person to care for the ground, but a mist would rise up from the earth and water all the ground.

The LORD God caused every beautiful tree and every tree that was good for food to grow out of the ground. In the middle of the garden, God put the tree that gives life and also the tree that gives the knowledge of good and evil.
