The table below presents two contradictory verses / verselets. Both verses speak about female slaves. The underlined words highlight the contradiction. One verse says the woman goes out after 6 years while the other verse states the woman belongs to her master We see the contradiction---which is it? Do women remain slaves or do they go free at six? Rashi simply resolves this contradiction using the 2 aspects method: Jewish female slaves go free at 6 years; however, non-Jewish female slaves remain with their master.

Summary	Verse / Source	Text of verse / Source
Both male/female Jewish slaves are freed at 6 years	Dt15-12	And if your brother, a Hebrew man, or a Hebrew woman, is sold to you, and serves you six years; then in the seventh year you shall let him go free from you.
The [non Jewish] female slave remains with her master	Ex21-04a	If his master give him a wife, and she bear him sons or daughters; the wife and her children shall be her master's, and he shall go out by himself.
Resolution:	2 Aspects	Jewish female slaves go free at 6 years Non-Jewish female slaves remain with their master.

Advanced Rashi: The literal language of Rashi shows more clearly the underlying logic: When the verse says If his master give him a wife it could refer to either a non-Jewish or Jewish woman. Since however the verse continues He goes free but the woman remains with the master and another verse explicitly states that ....Jewish female slaves...go free in the seventh year I therefore conclude that the verse must be speaking about a non-Jewish wife that the master gives him. In other words Rashi does not emphasize contradiction but rather describes the derivation as selection between competing alternatives. This alternative viewpoint helps us understand the contradiction Rashi rule.
