It was considered sinful for an Israel to marry a Canaanite or anyone from a different people group. This is why Samson's parents did not want him to marry a Philistine woman. They use rhetorical questions to convince him that he is sinning. This woman caused Samson many problems. (See: [[rc://en/tw/dict/bible/kt/sin]] and [[rc://en/ta/man/translate/figs-rquestion]])
