Adam Clarke on Isaiah 18:5

The flower "The blossom" - Hebrews her blossom; נצה nitstsah, that is, the blossom of the vine, גפן gephen, vine, understood, which is of the common gender. See Gen 40:10. Note, that by the defective punctuation of this word, many interpreters, and our translators among the rest, have been led into a grievous mistake, (for how can the swelling grape become a blossom?) taking the word נצה nitstsah for the predicate; whereas it is the subject of the proposition, or the nominative case to the verb.
