Amos 2:7

2:7 go in to the same girl. Amos decries uncontrolled sexual passion. Such behavior was contrary to God’s original intention (Gen. 2:21–24; Matt. 19:4–6), and it profaned God’s holy name (Lev. 18:24). The Mosaic law prohibited sexual union among persons closely related by blood (Lev. 18:6–18); while the Mosaic law does not mention this specific situation (the sharing of a common prostitute), the basic principle would still apply.
