正如你所说的，这种情况在谚语中很常见。又如：

He who does not work , neither shall he eat. 不劳动者不得食。

He who wills success is halfway to it.  热切争取成功等于成功了一半。

He who doesn't reach the Great Wall is not a true man. 不到长城非好汉。

▲除谚语外，定语从句也可以修饰人称代词。下面是《21世纪大英汉词典》和iCIBA中的几个词典例句，供参考：

You must honour him who will honour you. 你必须尊重别人，他才会尊重你。

You who are in power have only the means that money produces. 你们当权的人所有的只是金钱能买到的东西。

She who had always looked up to Kath had been talking about poor Kath. 她一直很尊敬凯斯·一直谈论贫穷。

They who listen to such music may expect to have to pay the piper. 倾听这种音乐的人则势必要出钱。

 I, who am beyond praise and blame, tell you a word. 我作为一个功罪两不沾的人，告诉你一句话。
