And thy food which thou shalt eat shall be by weight, {h} twenty shekels a day: from time to time shalt thou eat it.

(h) Which make a pound.

Wesley's Notes

4:10 By weight - Not as much as you will, but a small pittance delivered by weight to all. Twenty shekels - Ten ounces: scarce enough to maintain life. From time to time - At set hours this was weighed out.

Jamieson-Fausset-Brown Bible Commentary

10. twenty shekels-that is, little more than ten ounces; a scant measure to sustain life (Jer 52:6). But it applies not only to the siege, but to their whole subsequent state.

Matthew Henry's Concise Commentary

4:9-17 The bread which was Ezekiel's support, was to be made of coarse grain and pulse mixed together, seldom used except in times of urgent scarcity, and of this he was only to take a small quantity. Thus was figured the extremity to which the Jews were to be reduced during the siege and captivity. Ezekiel does not plead, Lord, from my youth I have been brought up delicately, and never used to any thing like this; but that he had been brought up conscientiously, and never had eaten any thing forbidden by the law. It will be comfortable when we are brought to suffer hardships, if our hearts can witness that we have always been careful to keep even from the appearance of evil. See what woful work sin makes, and acknowledge the righteousness of God herein. Their plenty having been abused to luxury and excess, they were justly punished by famine. When men serve not God with cheerfulness in the abundance of all things, God will make them serve their enemies in the want of all things.
