Luke 7.36-50 tells of the anointing of Jesus' feet. Luke 8.1ff. describes Jesus' "preaching and bringing the good news of the kingdom of God". Perhaps there is something lurking behind Luke's narrative.
Recall Isaiah 52.7: "How beautiful upon the mountains are the feet of him who brings good news , who publishes peace, who brings good news of good, who publishes salvation, who says to Zion, 'Your God reigns' " (emphasis added).
Is Luke therefore suggesting here that Jesus, whose feet were anointed, is then the "lovely one" who preaches the "good news" as spoken of by Isaiah?
I also find it interesting that the latter half of Isaiah 52 speaks of ritual purity, culminating into the refrain:
"Behold, my servant shall prosper, he shall be exalted and lifted up, and shall be very high. As many were astonished at him -- his appearance was so marred, beyond human semblance, and his form beyond that of the sons of men -- so shall he startle many nations; kings shall shut their mouths because of him; for that which has not been told them they shall see, and that which they have not heard they shall understand." (52.13-15).
