Son père et sa mère lui dirent: "Est-ce qu’il n’y a pas de femme dans ta parenté ou dans le reste de notre peuple, que tu ailles en chercher une parmi ces Philistins incirconcis?" Samson répondit à son père: "Procure-moi celle-là, puisque celle-là me plaît."
Sefer HaChinukh
To not wander after the thoughts of the heart and the vision of the eyes: That we not wander after the thoughts of the heart and the vision of the eyes, as it is stated (Numbers 15:39), “Do not wander after your hearts and your eyes.” The content of this negative commandment is that we were prevented from dedicating our thoughts to think about opinions that are antithetical to the ones on which the Torah is built, as that may lead one to apostasy. Rather, if the spirit to pursue these bad opinions should arise, one should minimize his thinking about them, and redouble his efforts to contemplate the true and good ways of the Torah. Similarly, one should not pursue the things he sees; and included in this is that we not pursue after the desires of this world, for in the end they are evil and “there is much shame and wrath.” This is [the meaning of] what they, may their memory be blessed, said (Berakhot 12b), “‘Do not stray after your hearts’ refers to apostasy. ‘After your eyes’ refers to licentiousness, as it is stated (Judges 14:3), ‘And Samson said to his father, “Take her for me, as she is right in my eyes.”’”
