Charles Spurgeon Commentary John 12:2-3

"So they made him a supper there: and Martha served; but Lazarus was one of them that sat at meat with him. Mary therefore took a pound of ointment of pure nard, very precious, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odor of the ointment." — John 12:2-3 (ASV)

There they made him a supper; and Martha served: but Lazarus was one of them that sat at the table with him. Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped his feet with her hair: and the house was filled with the odour of the ointment.

All the members of the reunited family were present, Martha busy as usual with the domestic duties which fell to her share, Lazarus in close attendance upon the Master who had wrought so great a miracle upon him, and Mary in her own sweet and gracious way pouring out the wealth of her affection in honour of the Master.

And Martha served: but Lazarus was one of them that sat at the table with him. Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus.

The other evangelist said "anointed his head." And they are both right. She anointed his head and his feet.
