Some versions such as the UDB understand this word to refer to the one who loves the woman, but the ULB understands it to refer to the one whom the woman loves. See how you translated this in [Song of Solomon 1:13](../01/12.md).
"young women of Jerusalem." These young women could not hear her and were not present, but the woman speaks as if they were present and could hear her. See how you translated this in [Song of Solomon 2:7](../02/07.md). (See: [[rc://en/ta/man/translate/figs-apostrophe]])
