Adam Clarke on Psalms 81:16

With the finest of the wheat - מחלב חטה mecheleb chittah; literally, with the fat of wheat, as in the margin.

Honey out of the rock - And he fed thaim of the grese of whete: And of the hony stane he thaim filled. Old Psalter. Thus paraphrased: "He fed thaim with the body of Criste and gastely understandyng; and of hony that ran of the stane, that is, of the wisedome that is swete to the hert." Several of the fathers understand this place of Christ.
