'Family' in the Bible

“When brothers live together and one of them dies and has no son, the wife of the deceased shall not be married outside the family to a strange man. Her husband’s brother shall go in to her and take her to himself as wife and perform the duty of a husband’s brother to her.

so that there will not be among you a man or woman, or family or tribe, whose heart turns away today from the Lord our God, to go and serve the gods of those nations; that there will not be among you a root bearing poisonous fruit and wormwood.
