Love is so strong that it is like a fire that is so hot that it cannot be put out even with an ocean full of water. (See: [[rc://en/ta/man/jit/figs-metaphor]])
Love never changes and always stays the same so it is like something that not even a powerful flood can move. (See: [[rc://en/ta/man/jit/figs-metaphor]])
Love is so valuable that even all a man's possessions would not be enough to buy love. Some versions translate this as "Even if a man ... he would be utterly despised."
This can be translated in active form. Alternate translation: "people would completely despise it" or "people would harshly ridicule him" (See: [[rc://en/ta/man/jit/figs-activepassive]])
