And thou shalt eat the fruit of thine own body, the flesh of thy sons and of thy daughters, which the LORD thy God hath given thee, in the siege, and in the straitness, wherewith thine enemies shall distress thee:

King James Translators' Notes

body: Heb. belly

Jamieson-Fausset-Brown Bible Commentary

53-57. And thou shalt eat the fruit of thine own body-(See 2Ki 6:29; La 4:10). Such were the dreadful extremities to which the inhabitants during the siege were reduced that many women sustained a wretched existence by eating the flesh of their own children. Parental affection was extinguished, and the nearest relatives were jealously, avoided, lest they should discover and demand a share of the revolting viands.

Matthew Henry's Concise Commentary

28:45-68 If God inflicts vengeance, what miseries his curse can bring upon mankind, even in this present world! Yet these are but the beginning of sorrows to those under the curse of God. What then will be the misery of that world where their worm dieth not, and their fire is not quenched! Observe what is here said of the wrath of God, which should come and remain upon the Israelites for their sins. It is amazing to think that a people so long the favourites of Heaven, should be so cast off; and yet that a people so scattered in all nations should be kept distinct, and not mixed with others. If they would not serve God with cheerfulness, they should be compelled to serve their enemies. We may justly expect from God, that if we do not fear his fearful name, we shall feel his fearful plagues; for one way or other God will be feared. The destruction threatened is described. They have, indeed, been plucked from off the land, ver. 63. Not only by the Babylonish captivity, and when Jerusalem was destroyed by the Romans; but afterwards, when they were forbidden to set foot in Jerusalem. They should have no rest; no rest of body, ver. 65, but be continually on the remove, either in hope of gain, or fear of persecution. No rest of the mind, which is much worse. They have been banished from city to city, from country to country; recalled, and banished again. These events, compared with the favour shown to Israel in ancient times, and with the prophecies about them, should not only excite astonishment, but turn unto us for a testimony, assuring us of the truth of Scripture. And when the other prophecies of their conversion to Christ shall come to pass, the whole will be a sign and a wonder to all the nations of the earth, and the forerunner of a general spread of true christianity. The fulfilling of these prophecies upon the Jewish nation, delivered more than three thousand years ago, shows that Moses spake by the Spirit of God; who not only foresees the ruin of sinners, but warns of it, that they may prevent it by a true and timely repentance, or else be left without excuse. And let us be thankful that Christ hath redeemed us from the curse of the law, by being made a curse for us, and bearing in his own person all that punishment which our sins merit, and which we must otherwise have endured for ever. To this Refuge and salvation let sinners flee; therein let believers rejoice, and serve their reconciled God with gladness of heart, for the abundance of his spiritual blessings.
