The Daily Mitzvah schedule runs parallel to the daily study of 3 chapters of Maimonides' 14-volume code. There are instances when the Mitzvah is repeated a few days consecutively while the exploration of the same Mitzvah continues in the in-depth track.

Exodus 21:10 "He shall not diminish her food, her clothing, or rights of marriage"

When a master (or his son) marries his Jewish maidservant, he must treat her properly.

The Torah cautions him not to neglect her rights and provide her with all her needs. This Negative Mitzvah applies not only to a maidservant, but any Jewish wife.
