Charles Ellicott Commentary Matthew 22:4

"Again he sent forth other servants, saying, Tell them that are bidden, Behold, I have made ready my dinner; my oxen and my fatlings are killed, and all things are ready: come to the marriage feast." — Matthew 22:4 (ASV)

My dinner—The Greek word points to a morning meal, as contrasted with the “supper,” or evening meal; but, like all such words (for example, our own word “dinner”), it was applied over time to meals at very different hours. In Homer, it is used for food taken at sunrise; in later authors, for the noon meal.

My oxen and my fatlings are killed—These words point, using imagery that Isaiah had already used (Isaiah 25:6), to the spiritual blessings of peace and joy that Christ came to offer. The word for “fatlings” is nearly the same as the one used for the “fatted calf” in Luke 15:30.
