Deuteronomy 32:13-14
13 He made him ride on the high places of the earth, that he might eat the increase of the fields; and he made him to suck honey out of the rock, and oil out of the flinty rock;
14 Butter of kine, and milk of sheep, with fat of lambs, and rams of the breed of Bashan, and goats, with the fat of kidneys of wheat; and thou didst drink the pure blood of the grape.
The settling of them in a good land. This was done in part already, in the happy planting of the two tribes and a half, an earnest of what would speedily and certainly be done for the rest of the tribes.
They were blessed with glorious victories over their enemies (v. 13): He made him ride on the high places of the earth, that is, he brought him on with conquest, and brought him home with triumph. He rode over the high places or strong holds that were kept against him, sat in ease and honour upon the fruitful hills of Canaan. In Egypt they looked mean, and were so, in poverty and disgrace; but in Canaan they looked great, and were so, advanced and enriched; they rode in state, as a people whom the King of kings delighted to honour.
With great plenty of all good things. Not only the ordinary increase of the field, but, which was uncommon, Honey out of the rock, and oil out of the flinty rock, which may refer either to their miraculous supply of fresh water out of the rock that followed them in the wilderness, which is called honey and oil, because the necessity they were reduced to made it as sweet and acceptable as honey and oil at another time. Or, to the great abundance of honey and oil they should find in Canaan, even in those parts that were least fertile. The rocks in Canaan should yield a better increase than the fields and meadows of other countries. Other productions of Canaan are mentioned, v. 14. Such abundance and such variety of wholesome food (and every thing the best in its kind) that every meal might be a feast if they pleased: excellent bread made of the best corn, here called the kidneys of the wheat (for a grain of wheat is not unlike a kidney), butter and milk in abundance, the flesh of cattle well fed, and for their drink, no worse than the pure blood of the grape; so indulgent a Father was God to them, and so kind a benefactor. Ainsworth makes the plenty of good things in Canaan to be a figure of the fruitfulness of Christ’s kingdom, and the heavenly comforts of his word and Spirit: for the children of his kingdom he has butter and milk, the sincere milk of the word; and strong meat for strong men, with the wine that makes glad the heart.
