Commentary for Proverbs 1:12

let us swallow them up The innocent when they are alive.

like the grave which swallows up the entire body.

and the whole ones Heb. ותמימים. This is not an expression of righteous men, but an expression of whole ones. Let us swallow them up when they are whole, like a man who descends into a pit when he is whole; i.e., when they are still wealthy, let us slay them and inherit their property.
