And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.

The manna and the water which flowed from the rock are called spiritual because they were formed not according to the law of nature but by the power of God working independently of the natural elements. They were created for a time as figures of what we now eat and drink in remembrance of Christ the Lord. Commentary on Paul’s Epistles.
