'Blessed' in the Bible

"Most blessed of women be Ja'el, the wife of Heber the Ken'ite, of tent-dwelling women most blessed.

And the woman bore a son, and called his name Samson; and the boy grew, and the LORD blessed him.

And he said to his mother, "The eleven hundred pieces of silver which were taken from you, about which you uttered a curse, and also spoke it in my ears, behold, the silver is with me; I took it." And his mother said, "Blessed be my son by the LORD."
