'Blessed are' in the Bible

Blessed is the one who reads the words of this prophecy aloud, and blessed are those who hear and obey the things written in it, because the time is near!

Then I heard a voice from heaven say, "Write this: 'Blessed are the dead, those who die in the Lord from this moment on!'" "Yes," says the Spirit, "so they can rest from their hard work, because their deeds will follow them."

Then the angel said to me, "Write the following: Blessed are those who are invited to the banquet at the wedding celebration of the Lamb!" He also said to me, "These are the true words of God."

Blessed are those who wash their robes so they can have access to the tree of life and can enter into the city by the gates.
