12 and now, your daughters ye do not give to their sons, and their daughters ye do not take to your sons, and ye do not seek their peace, and their good -- unto the age, so that ye are strong, and have eaten the good of the land, and given possession to your sons unto the age.
12
Therefore, do not give your daughters in marriage to their sons or take their daughters for your sons. Do not seek a treaty of friendship with them at any time, that you may be strong and eat the good things of the land and leave it to your children as an everlasting inheritance.’
