Deuteronomy 24:5 "Neither shall he be charged with any business"

The Torah tells us that a bridegroom must be excused from the army during the first year of his marriage.

He should be free to concentrate upon setting up his home and creating a pleasant atmosphere for his new wife. (See Positive Mitzvah 214).

We are cautioned not to assign any military service or any other duties to him during this first year of his marriage.
