'Blessed' in the Bible

Jethro said, "Blessed be Yahweh, who has delivered you out of the hand of the Egyptians, and out of the hand of Pharaoh; who has delivered the people from under the hand of the Egyptians.

for in six days Yahweh made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore Yahweh blessed the Sabbath day, and made it holy.

Moses saw all the work, and behold, they had done it as Yahweh had commanded, even so had they done it: and Moses blessed them.
