Deu 23:10-13 | KD | STEP | The person who had become unclean through a nightly occurrence, was to go out of the camp and remain there till he had cleansed himself in the evening. On the journey through the desert, none but those who were affected with uncleanness of a longer duration were to be removed from the camp (Num 5:2) but when they were encamped, this law was to apply to even lighter defilements.

‏ Deuteronomy 23:10-13

The person who had become unclean through a nightly occurrence, was to go out of the camp and remain there till he had cleansed himself in the evening. On the journey through the desert, none but those who were affected with uncleanness of a longer duration were to be removed from the camp (Num 5:2) but when they were encamped, this law was to apply to even lighter defilements. Deu 23:12-13

The camp of war was also not to be defiled with the dirt of excrements. Outside the camp there was to be a space or place (יד, as in Num 2:17) for the necessities of nature, and among their implements they were to have a spade, with which they were to dig when they sat down, and then cover it up again. יתד, generally a plug, here a tool for sticking in, i.e., for digging into the ground.
