The sense of smell

Psalm 115:5-7 describes some characteristics of idols, contrasting them with God.

They have mouths, but do not speak;
    eyes, but do not see.
They have ears, but do not hear;
    noses, but do not smell.
They have hands, but do not feel;
    feet, but do not walk;
    and they do not make a sound in their throat.

We all know that God sees and hears everything that happens and he has the ability to speak and act, but he has a sense of smell too.  The first mention of it is found in Genesis 8:20-22.
