'Relatives' in the Bible

Moses called also to Mishael and Elzaphan, the sons of Aaron’s uncle Uzziel, and said to them, “Come forward, carry your relatives away from the front of the sanctuary to the outside of the camp.”

You shall not uncover the nakedness of a woman and of her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness; they are blood relatives. It is lewdness.

except for his relatives who are nearest to him, his mother and his father and his son and his daughter and his brother,

or his uncle, or his uncle’s son, may redeem him, or one of his blood relatives from his family may redeem him; or if he prospers, he may redeem himself.
