Whoever causes the upright to go astray in an evil way, he will fall into his own trap; but the blameless will inherit good.

And he will be a sanctuary; but for a stone of stumbling and for a rock that makes them fall to both the houses of Israel, for a trap and for a snare to the inhabitants of Jerusalem.

Can a bird fall in a trap on the earth, where no snare is set for him? Does a snare spring up from the ground, when there is nothing to catch?
