'Happy' in the Bible

To those who are happy beyond measure when they reach their graves?

Behold, happy is the man whom God correcteth: therefore despise not thou the chastening of the Almighty:

For the ear heard, and declareth me happy, And the eye hath seen, and testifieth to me.

"Have I rejoiced in the destruction of those who hate me, or have I been happy that evil caught up with him?

If you have anything to say, answer me; speak up, because I'd be happy to vindicate you.
