'Lord's' in the Bible

With nothing I came out of my mother's body, and with nothing I will go back there; the Lord gave and the Lord has taken away; let the Lord's name be praised.

And the Lord's blessing was greater on the end of Job's life than on its start: and so he came to have fourteen thousand sheep and goats, and six thousand camels, and two thousand oxen, and a thousand she-asses.
