'Ambush' in the Bible

If they say, “Come with us;Let us lie in wait to shed blood,Let us ambush the innocent without cause;

But [when these people set a trap for others] they lie in wait for their own blood;They set an ambush for their own lives [and rush to their destruction].

At times she was in the streets, at times in the market places,Lurking and setting her ambush at every corner.
