Song of Songs 8:6-7 - The Nature Of Genuine Romantic Love
6 O set me as a seal upon thine heart, and as a seal upon thine arm: for love is mighty as the death, and jealousy as the hell. Her coals are of fire, and a very flame of the LORD: 7 so that many waters are not able to quench love, neither may the streams drown it. Yea, if a man would give all the good of his house for love, he should count it nothing.
