Genesis 34:20-23

20So Hamor and his son Shechem went to the gate of the city. They spoke to their men there.

21They said, ‘Jacob's family are our friends. Let them live in our land, and buy and sell things. This land is big enough for them and us. We can marry their daughters, and they can marry our daughters.

22But we must do the one thing that they have asked us to do. We must circumcise all our males in the same way that they do. If we do that, they will agree to live among us.

23Then their things and their animals will all become our things. So we should agree to be circumcised, as they ask. Then they will live among us.’
