The changing lines of hexagram 49
| Line | Chinese | Legge |
|---|---|---|
| 3 | 征凶，貞厲，革言三就，有孚。 | The third line, undivided, shows that action taken by its subject will be evil. Though he be firm and correct, his position is perilous. If the change (he contemplates) have been three times fully discussed, he will be believed in. |
| 4 | 悔亡，有孚改命，吉。 | The fourth line, undivided, shows occasion for repentance disappearing (from its subject). Let him be believed in; and though he change (existing) ordinances, there will be good fortune. |
| 6 | 君子豹變，小人革面，征凶，居貞吉。 | The sixth line, divided, shows the superior man producing his changes as the leopard (does when he) changes (his spots), while small men change their faces (and show their obedience). To go forward (now) would lead to evil, but there will be good fortune in abiding firm and correct. |
