Charles Ellicott Commentary Ezekiel 45:13

"This is the oblation that ye shall offer: the sixth part of an ephah from a homer of wheat; and ye shall give the sixth part of an ephah from a homer of barley;" — Ezekiel 45:13 (ASV)

The oblation: Ezekiel 45:13–16 provide for a regular tax to be paid to the prince, so that he may furnish the required offerings at the sanctuary. This, like the oblation of land (Ezekiel 45:1), is described as a “heave offering,” and was the sixtieth part of the grain, the hundredth of the oil, and the two-hundredth of the flock, all being from the year’s increase.
