And it is written: “As often as ye eat this bread, and drink this cup, ye do shew the Lord's death till He come” (1 Corinthians 11:26).
The Shepherd supplies all our needs in the presence of our enemies. Now it is more than rest or work—it is conflict. He provides for us here in this world. It is wilderness food—the manna of His promise, and water out of the Rock. We eat it as the Israelites did in haste, staff in hand, and ready to march on.
But the day is coming when the Good Shepherd will call us to the great supper in His kingdom.At feasts in Bible times, the heads of the distinguished guests were
anointed with perfumed oil. The woman in the gospel story poured the box
of precious ointment upon the head of our Lord, (Matthew 26:6-7) a
custom which the host who had invited Him had shamefully neglected. So,
too, the very sheep of the Lord's pasture are to be oil-anointed guests." BibleInfo
