Shemos. Moshe Rabbeinu's Shidduch.

Rabbeinu Bachay asks, why did Moshe want to marry a daughter of a priest of avodah zora, and why specifically Yisro? He explains that Moshe was a hunted man. There was a warrant out for his arrest for the murder of a government official. Moshe Rabbeinu knew that Pharaoh would arrest and imprison him at the first opportunity. Therefore he sought out a ‘kohen’, a priest. The priests, who owned their own property, as it says in the end of the previous parshah, were, to some degree, autonomous, less subject to royal threats and pressure. This made a marriage to a kohen's daughter a wise choice. Among Kohanim, he specifically chose Yisro because Yisro had seven daughters. A man that has seven daughters to marry off will not be too particular about scrutinizing a suitor's credentials or protesting a shidduch because the potential chassan has a tiny little legal problem in his background.
