'Blessed' in the Bible

Blessed is he that reads, and they that hear the words of the prophecy, and keep the things written in it; for the time is near.

And I heard a voice out of the heaven saying, Write, Blessed the dead who die in the Lord from henceforth. Yea, saith the Spirit, that they may rest from their labours; for their works follow with them.

(Behold, I come as a thief. Blessed is he that watches and keeps his garments, that he may not walk naked, and that they may not see his shame.)

And he says to me, Write, Blessed are they who are called to the supper of the marriage of the Lamb. And he says to me, These are the true words of God.

Blessed and holy he who has part in the first resurrection: over these the second death has no power; but they shall be priests of God and of the Christ, and shall reign with him a thousand years.

And behold, I come quickly. Blessed is he who keeps the words of the prophecy of this book.

Blessed are they that wash their robes, that they may have right to the tree of life, and that they should go in by the gates into the city.
