'Blessed' in the Bible

And thou hast sworn -- Jehovah liveth, In truth, in judgment, and in righteousness, And blessed themselves in Him have nations, And in Him they boast themselves.

Blessed is the man who trusteth in Jehovah, And whose confidence hath been Jehovah.

Cursed is the day in which I was born, The day that my mother bare me, Let it not be blessed!
