[C]ursed [is] the ground for thy sake; in sorrow shalt thou eat [of] it all the days of thy life;
Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;
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.
-- Genesis 3:17 ff.
