Dust

And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.

In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.

And Joshua rent his clothes, and fell to the earth upon his face before the ark of the LORD until the eventide, he and the elders of Israel, and put dust upon their heads.

And there ran a man of Benjamin out of the army, and came to Shiloh the same day with his clothes rent, and with earth upon his head.

It came even to pass on the third day, that, behold, a man came out of the camp from Saul with his clothes rent, and earth upon his head: and so it was, when he came to David, that he fell to the earth, and did obeisance.

And David went up by the ascent of mount Olivet, and wept as he went up, and had his head covered, and he went barefoot: and all the people that was with him covered every man his head, and they went up, weeping as they went up.

And when they lifted up their eyes afar off, and knew him not, they lifted up their voice, and wept; and they rent every one his mantle, and sprinkled dust upon their heads toward heaven.

Wherefore I abhor myself, and repent in dust and ashes.

And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
