כַּ֭מַּיִם הַפָּנִ֣ים לַפָּנִ֑ים כֵּ֤ן לֵֽב־הָ֝אָדָ֗ם לָאָדָֽם׃
Como na água o rosto corresponde ao rosto, assim o coração do homem ao homem.
Rashi on Proverbs
As in water the face that you show it, it shows you.
Rashi on Proverbs
is the heart of a man to a man his friend. According to how much a man knows that his friend loves him, so he will show him his face.
