Genesis 27:39

Moved; yet not so as to repent of what he had done; for Esau found no place of repentance in his father's breast, although with tears he had sought it, (Hebrew xii. 17.) desiring to obtain the blessing of the first-born. (Haydock) --- In the fat, &c. Idumea was a barren country; and hence some would translate the Hebrew, "far from the fat...shall they dwelling be; but thou shalt live by the sword." Thus min often means from, as well as for in: my flesh is changed on account of the want of oil, Psalm cviii. 24. Hebrew, a pinguedine. (Calmet) --- But all the ancient versions agree with the Vulgate. So that we may say, the blessing of God made those barren regions supply the wants of the people abundantly; and so the Idumeans were to live by the sword, they would seize the rich habitations of their neighbours, (Haydock) and thus obtain a country rendered fertile without their labour. (Menochius)
