Charles Spurgeon Commentary Matthew 26:6-7

"Now when Jesus was in Bethany, in the house of Simon the leper, there came unto him a woman having an alabaster cruse of exceeding precious ointment, and she poured it upon his head, as he sat at meat." — Matthew 26:6-7 (ASV)

We do not know who Simon the leper was, nor whether this woman was Mary, the sister of Lazarus, though I believe she was the one who came to Jesus, having an alabaster box of very precious ointment, and poured it on his head, as he reclined at the table. The beauty of this woman’s act consisted in this: that it was all for Christ. All who were in the house could perceive and enjoy the perfume of the precious ointment, but the anointing was for Jesus only.

This is not the woman who anointed Christ's feet with ointment, but another of the holy women who ministered to him. I believe this was Mary, the sister of Lazarus, who came to Jesus, having an alabaster box of very precious ointment, and poured it on his head, as he sat at meat.
