'Blessed' in the Bible

Jethro said, “Blessed be the Lord, who has rescued you from the hand of the Egyptians and from the hand of Pharaoh, and who has rescued the people from under the hand of the Egyptians.

For in six days the Lord made the heavens and the earth, the sea and everything that is in them, and He rested (ceased) on the seventh day. That is why the Lord blessed the Sabbath day and made it holy [that is, set it apart for His purposes].

And Moses [carefully] inspected all the work, and behold, they had done it; just as the Lord had commanded, so had they done it. So Moses blessed them.
