'In the Name of the Lord' in the Bible

"Listen to this, house of Jacob, you who are called by the name of Israel, and who have come forth from Judah's loins; you who swear oaths in the name of the LORD and invoke the God of Israel but not in truth, nor in good faith.

Who is among you that feareth the LORD, that obeyeth the voice of his servant, that walketh in darkness, and hath no light? let him trust in the name of the LORD, and stay upon his God.
