SB 6.14.36

krcchra-labdhe ’tha rajarses
 tanaye ’nudinam pituh
yatha nihsvasya krcchrapte
 dhane sneho ’nvavardhata
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When a poor man gets some money after great difficulty, his affection for the money increases daily. Similarly, when King Citraketu, after great difficulty, received a son, his affection for the son increased day after day.
