And when Boaz had eaten and drunk, and his heart was merry, he went to lie down at the end of the heap of corn: and she came softly, and uncovered his feet, and laid her down. (Ruth 3:7)
A Targum reads, “He [Boaz] blessed the name of Jehovah.” The word here translated “merry” is often used to express happiness and a sense of well-being, and in no way implies that Boaz was intoxicated. With a plentiful harvest at hand, following the years of famine, he could well be thankful for the bounties of heaven.
