The way of peace they know not; and there is no judgment in their goings: they have made them crooked paths: whosoever goeth therein shall not know peace.
The way of peace they know not - whether in relation to God, to their own conscience, or to their fellow-men (Isaiah 57:20-21).
And (there is) no judgment in their goings - no justice.
They have made them crooked paths - the opposite of "straightforward" (Proverbs 2:15; Proverbs 28:18).
