Please help me understand the meaning of this phrase (Gen 2.24:
עַל־כֵּן יַעֲזָב־אִישׁ אֶת־אָבִיו וְאֶת־אִמּוֹ וְדָבַק בְּאִשְׁתּוֹ וְהָיוּ לְבָשָׂר אֶחָד׃
Hence a man leaves his father and mother and clings to his wife so that they become one flesh.
As I don't see any source that a man should cling to his parents in the first place, the only possible connection that links kids to their parents is the commandment to honor them (inexistent with Gentiles), so I don't understand the meaning of leaving them.
So, besides the trivial and natural leaving the house, what is the meaning of "leaving his father and mother"?
