“And he came near, and kissed him: and he smelled the smell of his raiment, and blessed him, and said, See, the smell of my son is as the smell of a field which the LORD hath blessed: / Therefore God give thee of the dew of heaven, and the fatness of the earth, and plenty of corn and wine: / Let people serve thee, and nations bow down to thee: be lord over thy brethren, and let thy mother’s sons bow down to thee: cursed be every one that curseth thee, and blessed be he that blesseth thee.”
