4 What could have been done more to My vineyard [kerem], that I have not done in it? wherefore, when I looked that it should bring forth grapes [anavim], brought it forth wild grapes [b'ushim]?
Use of Wine in Scripture
Pleasant wine here represents obedience and the fruit of the spirit see Matt 21: 33-41, also wine represents Messiah's blood of the new covenant. And then there is wine to represent the Babylon-pagan teachings of the intoxicated and deluded priests of papism.
14 Therefore hell [Sheol] hath enlarged herself, and opened her mouth without measure [chok (limit)]: and their glory [nobility], and their multitude [masses], and their pomp [throngs], and he that rejoiceth [the reveler], shall descend into it.
... the Spirit speaks of Hades, by the name of Sheol, and as a female with a mouth that is insatiable -- Sheol is never satisfied (Prov. xxx. 15,16).
"My people are gone into captivity, because they have no knowledge; and their honorable men are famished, and their multitude dried up with thirst; therefore Sheol, or Hades, hath enlarged herself, and opened her mouth without measure: and their glory and their multitude, and their pomp, and he that rejoiceth, shall descend into it."
Though metaphorical, this is very intelligible. It predicted great destruction of all ranks and classes in Israel; and consequently, a great shovelling of them into the never filled receptacle of the dead. This insatiable nature of Sheol, or Hades, is the reason of her being styled "cruel."
Thus, "love is strong as Death; jealousy, cruel as Sheol" (Cant. viii. 6).
