'Hater' in the Bible

Or, Get me out of the power of my hater? or, Give money so that I may be free from the power of the cruel ones?

Let my hater be like the evil man, and let him who comes against me be as the sinner.

If I was glad at the trouble of my hater, and gave cries of joy when evil overtook him;

How may a hater of right be a ruler? and will you say that the upright Ruler of all is evil?
