'Prosper' in the Bible

and all the prophets are prophesying so, saying, 'Go up to Ramoth-Gilead, and prosper, and Jehovah hath given it into the hand of the king.'

And he cometh in unto the king, and the king saith unto him, 'Micaiah, do we go unto Ramoth-Gilead, to battle, or do we forbear?' and he saith unto him, 'Go up, and prosper, and Jehovah hath given it into the hand of the king.'
