7All floods enter into the sea, and the sea floweth not over the marks set of God; the floods turn again to the place from whence they come forth, that they flow out again. (All the rivers enter into the sea, and the sea floweth not over the boundaries set by God; the rivers return to the places from where they came forth, only so that they can flow out again.)
8All things be hard; a man may not declare those things by word (or a person cannot declare all of these things with words alone); the eye is not (ful)filled by sight, neither the ear is filled by hearing.
