a fugitive and a vagabond shalt thou be in the earth; being obliged to quit his former habitation, and remove to a place at some distance from the house of his father Adam, which was near the garden of Eden, as Aben Ezra observes; and to wander about from place to place, having no quiet settlement in anyone place: the Septuagint render it "groaning and trembling"; the guilt of his sin lay heavy on his conscience, and filled him with such horror and terror that he was continually sighing and groaning, and was seized with such a tremor that he shook in all his limbs; so the Arabic writers say, that he was trembling and quivering, and had a shaking in his head all the days of his life; and Aben Ezra observes, that there are some that say that the first of these words signifies to moan and lament; but it may be, it was not so much his sin, at least the evil of it, that he lamented, as the mischief that came by it, or the calamities and misfortunes it brought upon him.
