Ezekiel 4:10

And thy meat which thou shall eat shall be by weight, twenty shekels a day ,.... To eat bread by weight was a sign of a grievous famine; see Leviticus 26:26 ; a shekel, according to Josephus F9 Antiqu. l. 3. c. 8. sect. 2. , weighed four Attic drachms, or half an ounce, wherefore twenty shekels weighed ten ounces; so that the bread the prophet had to eat was but ten ounces a day:

from time to time shall thou eat it ; at the certain time of eating, or but once a day; from a set time in one day to the same in another; as from morning to morning, or from noon to noon, or from evening to evening; see Jeremiah 37:21 .
