'Blessed' in the Bible

And her mother in law said unto her, Where hast thou gleaned to day? and where wroughtest thou? blessed be he that did take knowledge of thee. And she shewed her mother in law with whom she had wrought, and said, The man's name with whom I wrought to day is Boaz.

And Naomi said unto her daughter in law, Blessed be he of the LORD, who hath not left off his kindness to the living and to the dead. And Naomi said unto her, The man is near of kin unto us, one of our next kinsmen.

And he said, Blessed be thou of the LORD, my daughter: for thou hast shewed more kindness in the latter end than at the beginning, inasmuch as thou followedst not young men, whether poor or rich.

And the women said unto Naomi, Blessed be the LORD, which hath not left thee this day without a kinsman, that his name may be famous in Israel.
