'Spareth' in the Bible

And be it still my consolation, Yea, let me exult in pain that spareth not, That I have not denied the words of the Holy One.

He that spareth his rod hateth his son; But he that loveth him chasteneth him betimes.

He that spareth his words hath knowledge; And he that is of a cool spirit is a man of understanding.

Through the wrath of Jehovah of hosts is the land burnt up; and the people are as the fuel of fire: no man spareth his brother.

And they shall be mine, saith Jehovah of hosts, even mine own possession, in the day that I make; and I will spare them, as a man spareth his own son that serveth him.
