You prepare a table before me
in the presence of my enemies;
you anoint my head with oil;
my cup overflows. — Psalm 23:5
David here is not remembering merely spiritual blessings and refreshment. He is recounting actual feasts at the house of God:
You shall observe the Feast of Weeks, the firstfruits of wheat harvest, and the Feast of Ingathering at the year’s end. Three times in the year shall all your males appear before the Lord God, the God of Israel. For I will cast out nations before you and enlarge your borders; no one shall covet your land, when you go up to appear before the Lord your God three times in the year. — Exodus 34:22-24
The new covenant feast is just that — a table and cup in the house of God, who rebukes those who would trample his bride (Ps. 68:28ff).
