'Shall Not Pity' in the Bible

And thou shall consume all the peoples that LORD thy God shall deliver to thee. Thine eye shall not pity them. Neither shall thou serve their gods, for that will be a snare to thee.

Thine eye shall not pity him, but thou shall put away the innocent blood from Israel, that it may go well with thee.

And thine eyes shall not pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
