Deuteronomy 24:9

6 No man shall take the mill or the upper millstone to pledge; for he takes [a man`s] life to pledge.

7 If a man be found stealing any of his brothers of the children of Israel, and he deal with him as a slave, or sell him; then that thief shall die: so shall you put away the evil from the midst of you.

8 Take heed in the plague of leprosy, that you observe diligently, and do according to all that the priests the Levites shall teach you: as I commanded them, so you shall observe to do.

9 Remember what Yahweh your God did to Miriam, by the way as you came forth out of Egypt.

10 When you do lend your neighbor any manner of loan, you shall not go into his house to get his pledge.

11 You shall stand outside, and the man to whom you do lend shall bring forth the pledge outside to you.

12 If he be a poor man, you shall not sleep with his pledge;
