Genesis 3:8

And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.

1. Adam and Eve heard the LORD God speaking in the garden in the cool part of the day (perhaps, either the morning, or the evening).
2. Adam and Eve believed, from the sounds they heard, that the LORD God was walking in the garden.
3. Adam and Eve apparently knew the LORD God as a being capable of walking and speaking.
4. In response to hearing the LORD God in the garden, Adam and Eve hid among the trees.
5. Adam and Eve were apparently nervous or fearful about meeting the LORD God again.
