Nehemiah 13:19

13:19 When the evening shadows began to fall on the gates of Jerusalem before the Sabbath, I ordered the doors to be closed. I further directed that they were not to be opened until after the Sabbath. I positioned some of my young men at the gates so that no load could enter on the Sabbath day.

Nehemiah 13:25

13:25 So I entered a complaint with them. I called down a curse on them, and I struck some of the men and pulled out their hair. I had them swear by God saying, “You will not marry off your daughters to their sons, and you will not take any of their daughters as wives for your sons or for yourselves!
