Reference for Kiddushin 64:11

יכול יעצים עיניו כמי שלא ראהו ת"ל תקום ויראת דבר המסור ללב נאמר בו (ויקרא יט, יד) ויראת מאלהיך

[implying], I ordered one to rise up only where it confers honour.<span class="x" onmousemove="('comment',' But no sense of being honoured is experienced when a person rises at a distance.');">²⁴</span> I might think that one must honour him with money,<span class="x" onmousemove="('comment',' I.e., by giving him money.');">²⁵</span> therefore it is written: 'thou shalt rise u and thou shalt honour': just as rising up involves no monetary loss, so does honouring also mean without monetary loss.
