Matthew Poole and continuators on Genesis 3:19

19. 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 :

(i. e.) Of thy Body: He mentions the Face, because there the sweat appears first and most. Or, with labour of Body or Brain, Eccles. 1. 13. and vexation of mind.

(i. e.) Get thy food and livelihood: Bread being put for all nourishment, as Gen. 18. 5. and 28. 20.

As to the constitution and original of thy Body. See Gen. 18. 27. Iob 1. 21. Psal. 103. 14.

Though upon thy obedience I would have preserved thy Body no less than thy Soul from all mortality, yet now having sinned thou shalt return unto dust in thy Body, whilst the immortal Spirit shall return unto God who gave it, Eccles. 12. 7. Thus thy end shall be as base as thy beginning.
