'Prosper' in the Bible

Keep the charge of the Lord your God, [that is, fulfill your obligation to] walk in His ways, keep His statutes, His commandments, His precepts, and His testimonies, as it is written in the Law of Moses, so that you may succeed in everything that you do and wherever you turn,

All the prophets were prophesying in the same way [to please Ahab], saying, “Go up to Ramoth-gilead and be successful, for the Lord will hand it over to the king.”

So when he came to the king, the king said to him, “Micaiah, shall we go against Ramoth-gilead in battle, or shall we not?” And he answered him, “Go up and be successful, for the Lord will hand it over to the king.”
