וְרָאִיתָ֙ בַּשִּׁבְיָ֔ה אֵ֖שֶׁת יְפַת־תֹּ֑אַר וְחָשַׁקְתָּ֣ בָ֔הּ וְלָקַחְתָּ֥ לְךָ֖ לְאִשָּֽׁה׃
네가 만일 그 포로 중의 아리따운 여자를 보고 연련하여 아내를 삼고자 하거든
Mei HaShiloach
And you desire her and take her as a wife, and you bring her etc and she shaves etc and takes off the clothes of captivity - this is that everything that finds grace in the eyes of Israel certainly has in it something good, yet, it is necessary to make many selections so as to know if this is true grace or some external trapping that met one's eye. That is why it commanded that she should distance herself from all externalities, and after that, if grace is still found in his eyes, then obviously something good is found in her.
