'Snare' in the Bible

But if thy right eye be a snare to thee, pluck it out and cast it from thee: for it is profitable for thee that one of thy members perish, and not thy whole body be cast into hell.

But Jesus turned and said to Peter, “Get behind Me, Satan! You are a stumbling block to Me; for you are not setting your mind on things of God, but on things of man.”

And if thy right hand be a snare to thee, cut it off and cast it from thee: for it is profitable for thee that one of thy members perish, and not thy whole body be cast into hell.
