Deuteronomy 32:14 - Joseph Benson’s Commentary on the Old and New Testaments

Milk of sheep Le Clerc renders it, Milk of sheep and goats; the Hebrew word signifying both. With fat of lambs Or, lambs well fatted. The fat, indeed, wherewith the inwards were covered was not to be eaten by them, but offered to God; yet that fat which was mixed with the flesh they might eat. Bashan A place famous for excellent cattle. Fat of kidneys of wheat With the finest of the grains of wheat, compared to kidneys in their shape and colour; or with large and plump corn, affording a plenty of flour. The pure blood of the grape This metaphor, as well as the preceding, is very elegant and natural, on account of the great resemblance between red wine and blood; and it is also a very animated expression.
