'Blessed Be the Lord' in the Bible

David said to Abigail, “Blessed be the Lord, the God of Israel, who sent you to meet me this day.

When David heard that Nabal was dead, he said, “Blessed be the Lord, who has pleaded the cause of my reproach [suffered] at the hand of Nabal and has kept His servant from [retaliating with] evil. For the Lord has returned the wickedness of Nabal on his own head.” Then David sent word to Abigail, proposing to take her as his wife.
