The 214th mitzvah is that we are commanded that a newlywed man should remain together with his wife for a full year. He shall not travel away, serve in a "conquering1 army," or take on any similar obligations. Rather, he shall gladden her for a full year beginning with the wedding day.
The source of this commandment is G‑d's statement2 (exalted be He), "[When a man takes a new bride...] he must remain free for his house for one year and gladden his bride."
The details of this mitzvah are explained in the eighth chapter of tractate Sotah.3
