מַ֣יִם רַבִּ֗ים לֹ֤א יֽוּכְלוּ֙ לְכַבּ֣וֹת אֶת־הָֽאַהֲבָ֔ה וּנְהָר֖וֹת לֹ֣א יִשְׁטְפ֑וּהָ אִם־יִתֵּ֨ן אִ֜ישׁ אֶת־כָּל־ה֤וֹן בֵּיתוֹ֙ בָּאַהֲבָ֔ה בּ֖וֹז יָב֥וּזוּ לֽוֹ׃ (ס)
眾水不能熄滅這愛，江河也不能將它沖沒；若有人拿他家中所有的財產來換這愛，他必被人全然藐視。
Duties of the Heart
3. One who volunteers towards doing the will of the one he loves with his money, body, and life, as the wise man said: "Many waters cannot quench love, neither can the floods drown it" (Shir HaShirim 8:7), and it is written about Yehonatan and David: "for he loved him as he loved his own soul" (Shmuel 20:17), and "wonderful was your love to me, passing the love of women" (Shmuel II 1:26).
