The fifth NINE, undivided, shows the difficulties in the way of (its subject's) dispensing the rich favours that might be expected from him. With firmness and correctness there will be good fortune in small things; (even) with them in great things there will be evil.
'Difficulty is experienced (by the subject of the fifth line) in bestowing his rich favours:' - the extent to which they reach will not yet be conspicuous.
