'Blessed is' in the Bible

David said to Abigail, "Blessed is Yahweh, the God of Israel, who sent you this day to meet me!

Blessed is your discretion, and blessed are you, that have kept me this day from blood guiltiness, and from avenging myself with my own hand.

When David heard that Nabal was dead, he said, "Blessed is Yahweh, who has pleaded the cause of my reproach from the hand of Nabal, and has kept back his servant from evil. Yahweh has returned the evildoing of Nabal on his own head." David sent and spoke concerning Abigail, to take her to him as wife.
