Ezra 9:11-12

Context
9:11 which you commanded us through your servants the prophets with these words: ²  ‘The land that you are entering to possess is a land defiled by the impurities of the local residents! ³  With their abominations they have filled it from one end to the other with their filthiness. 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 ⁴  forever.’
