Genesis 34:8-10

8But Hamor conferred with them, saying, “The soul of my son Shechem [deeply] longs for your daughter [and sister]. Please give her to him as his wife.

9And [beyond that] intermarry with us; give your daughters to us [as wives] and take our daughters for yourselves.

10In this way you shall live with us; the country will be open to you; live and do business in it and acquire property and possessions in it.”
