Exodus 21:7Deuteronomy 21:10-14Genesis 21:1425:6

The immediate cause of concubinage might be gathered from the conjugal histories of Abraham and Jacob (Genesis 1630;30 ). But in process of time the custom of concubinage degenerated, and laws were made to restrain and regulate it (Exodus 21:7-9 ).

Christianity has restored the sacred institution of marriage to its original character, and concubinage is ranked with the sins of fornication and adultery (Matthew 19:5-9; 1 Corinthians 7:2 ).
