I'll address the "dust". Yes, it is biblical, but it's not talking about dust as in the little white particles that float in the light, it's talking about dirt.

Genesis 2:7
    7 And God proceeded to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man came to be a living soul.


Genesis 3:19

    By the sweat of your face will you eat bread until you return to the ground, for out of it you were taken. For you are dust, and to dust you shall return.
