Deuteronomy 7:3-5

Young's Literal Translation

³ `And thou dost not join in marriage with them; thy daughter thou dost not give to his son, and his daughter thou dost not take to thy son,

⁵ `But thus thou dost to them: their altars ye break down, and their standing pillars ye shiver, and their shrines ye cut down, and their graven images ye burn with fire;
