Here’s an excerpt on a Jewish teaching on wealth vs. children.
The tribes of Reuven and Gad also showed a flawed orientation toward their children in valuing their possessions first, as seen in their request to Moshe: We will build here sheepfolds for our livestock, and cities for our children (Bamidbar, 32:16). Rashi notes, on the basis of Tanchuma 7, that They were more concerned about their possessions than about their sons and daughters, since they spoke first about their livestock and then about their children. Moshe corrected them by placing priorities in the proper order, telling them to first build for yourselves cities for your children and afterwards enclosures for your sheep (there, verse 24).
