'Blessed' in the Bible

Then was the secret revealed unto Daniel in a night vision. Then Daniel blessed the God of heaven.

Daniel answered and said, Blessed be the name of God for ever and ever: for wisdom and might are his:

Then Nebuchadnezzar spake, and said, Blessed be the God of Shadrach, Meshach, and Abednego, who hath sent his angel, and delivered his servants that trusted in him, and have changed the king's word, and yielded their bodies, that they might not serve nor worship any god, except their own God.

And at the end of the days I Nebuchadnezzar lifted up mine eyes unto heaven, and mine understanding returned unto me, and I blessed the most High, and I praised and honoured him that liveth for ever, whose dominion is an everlasting dominion, and his kingdom is from generation to generation:

Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days.
