Let us swallow them up alive] Without any sign of blood, as if they had died a naturall death: or, so as no man may know what is become of them. Thus they provide for their own safety: or, so suddenly, as if this went quick down their throat. See Psal. 124. as the grave] As the grave is never satiate, so the avarice of the wicked, and their cruelty hath no end, Chap. 30. 16.
