Parshas Ki Saitzai focuses primarily on a variety of interpersonal relationships and the need to be sensitive to the feelings of others.

The portion opens with the intriguing case of the gentile woman who is captured in battle. The Torah then moves on to list a wide variety of mitzvos. It discusses the firstborn son's special inheritance rights, and the case of the ben sorer u'moreh (wayward son). It teaches that one should return lost objects to their owners; “finders keepers, losers weepers” doesn’t apply in every case. Another Torah law requires that when one finds a bird's nest, he  must shoo the mother bird away and only then take the young birds for himself. This is called shiluach hakain.

The Torah promotes fidelity and respect in relationships. The case of the defamation of a newly married woman (a husband who falsely accuses his wife of not being faithful to him) is then discussed, followed by the prohibition of adultery and other forbidden relationships. The Torah then mentions the laws of divorce, the requirement to receive a Jewish bill of divorce (get), and the laws of Shana Rishona, the special attention a husband must accord his wife during the first year of marriage. Also discussed is the prohibition of kidnapping, and the mitzvah to pay workers in a timely fashion.

The Torah then says that special consideration must be given to widows and orphans. The portion concludes with the commandment to remember the atrocities that the Amalekite people committed against us just after we emerged from slavery in Egypt.
