'Blessed' in the Bible

Blessed is he that readeth, and they that hear the words of the prophecy, and keep the things that are written therein: for the time is at hand.

And I heard the voice from heaven saying, Write, Blessed are the dead who die in the Lord from henceforth: yea, saith the Spirit, that they may rest from their labors; for their works follow with them.

(Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walked naked, and they see his shame.)

And he saith unto me, Write, Blessed are they that are bidden to the marriage supper of the Lamb. And he saith unto me, These are true words of God.

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

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

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