'Bless' in the Bible

And David returned to bless his household. And Michal the daughter of Saul came out to meet David, and said, How honourable did the king of Israel make himself to-day, who uncovered himself to-day in the eyes of the handmaids of his servants, as one of the lewd fellows shamelessly uncovers himself!

and now let it please thee to bless the house of thy servant, that it may be before thee for ever; for thou, Lord Jehovah, hast spoken it; and with thy blessing shall the house of thy servant be blessed for ever.

And David said to the Gibeonites, What shall I do for you? and with what shall I make atonement, that ye may bless the inheritance of Jehovah?
