'Sharp' in the Bible

And you, son of man, have no fear of them or of their words, even if sharp thorns are round you and you are living among scorpions: have no fear of their words and do not be overcome by their looks, for they are an uncontrolled people.

And thou, son of man, take thee a sharp knife, take thee a barber's rasor, and cause it to pass upon thine head and upon thy beard: then take thee balances to weigh, and divide the hair.

Son of man, say as a prophet, These are the words of the Lord: Say, A sword, a sword which has been made sharp and polished:

It has been made sharp to give death; it is polished so that it may be like a thunder-flame: ...

And I have given it to the polisher so that it may be taken in the hand: he has made the sword sharp, he has had it polished, to put it into the hand of him who gives death.

Be sharp! Attack on the right, or parry to your left, wherever you point your sword.

"The house of Israel will never again suffer from painful briers and sharp thorn bushes that surround them on every side, and they will learn that I am the LORD.
