'Bless' in the Bible

Then David returned to bless his household. Michal the daughter of Saul came out to meet David, and said, "How glorious the king of Israel was today, who uncovered himself today in the eyes of the handmaids of his servants, as one of the vain fellows shamelessly uncovers himself!"

Now therefore let it please you to bless the house of your servant, that it may continue forever before you; for you, Lord Yahweh, have spoken it. Let the house of your servant be blessed forever with your blessing."

then Toi sent Joram his son to king David, to Greet him, and to bless him, because he had fought against Hadadezer and struck him: for Hadadezer had wars with Toi. [Joram] brought with him vessels of silver, and vessels of gold, and vessels of brass:

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