Ezra 9:12

9:12 Therefore do not give your daughters in marriage to their sons, and do not take their daughters in marriage for your sons. Do not ever seek their peace or welfare, so that you may be strong and may eat the good of the land and may leave it as an inheritance for your children forever.’

Proverbs 13:22

13:22 A benevolent person leaves an inheritance for his grandchildren,

but the wealth of a sinner is stored up for the righteous.
