Albert Barnes on Luke 15:16

The husks. The word husks with us denotes the outward covering of corn. In this there is little nourishment, and it is evident that this is not intended here; but the word used here denotes not only husks, but also leguminous plants, as beans, &c. It is also used to denote the fruit of a tree called the carob or kharub-tree, which is common in Ionia, Syria, and Rhodes. The tree is more bushy and thick-set than the apple-tree, and the leaves are larger and of a much darker green. The following is Dr. Thomson's description of the fruit of this tree (The Land and the Book, vol. i.p. 22):

"The husks-- a mistranslation--are fleshy pods, somewhat like those of the locust-tree, from six to ten inches long and one broad, laid inside with a gelatinous substance, not wholly unpleasant to the taste when thoroughly ripe. I have seen large orchards of this kharub in Cyprus, where it is still the food which the swine do eat. The kharub is often called St. John's Bread, and also Locust-tree, from a mistaken idea about the food of the Baptist in the wilderness." The cut will give an idea of these pods, or husks as they are called in our translation.

No man gave unto him. Some have understood this as meaning "no one gave him anything -- any bread or provisions;" but the connection requires us to understand it of the "husks." He did not go a begging --his master was bound to provide for his wants; but the provision which he made for him was so poor that he would have preferred the food of the swine. He desired a portion of their food, but that was not given him. A certain quantity was measured out for them, and he was not at liberty to eat it himself. Nothing could more strikingly show the evil of his condition, or the deep degradation, and pollution, and wretchedness of sin.
