Mbh 13.62.4b

That man who having promised to make a gift of earth does not actually make it, or who having made a gift takes it back, has to pass a long time, in great misery in consequence of being tied with the noose of Varuna at the command of Death. Those men have never to go to Yama who honour and worship those foremost of Brahmanas that pour libations every day on their domestic fire, that are always engaged in the performance of sacrifices, that have scanty means of livelihood, and that receive with hospitality every guest seeking shelter in their abodes. The king, O Purandara, should free himself from the debt he owes to the Brahmanas and protect the helpless and the weak belonging to the other orders. The king should never resume, O chief of the deities, earth that has been given away by another unto a Brahmana, O ruler of the celestials, that is destitute of the means of life.[332] The tears that would fall from the eyes of such cheerless and destitute Brahmanas in consequence of their lands being taken back are capable of destroying the ancestors and descendants to the third generation of the resumer. That man who succeeds by his endeavours in re-establishing a king driven away from his kingdom, obtains residence in heaven and is much honoured by the denizens thereof. That king who succeeds in making gifts of earth with such crops standing thereon as sugar-cane or barley or wheat, or with kine and horses and other draft cattle,--earth that has been won with the might of the giver's arms,--that has mineral wealth in its bowels and that is covered with every kind of wealth of the surface, wins inexhaustible regions of felicity in the next world, and such a king it is that is said to perform the earth-sacrifice. That king who makes a gift of earth becomes washed of every sin and is, therefore, pure and approved of the righteous. In this world he is highly honoured and applauded by all righteous men.
