“You must have just balances.” Leviticus 19:35 commanded people to have honest weights and measures. The fact that Ezekiel has to remind the people of that shows that they were acting unrighteously in their business deals; just more of the sin that the people of Judah were involved in during the time of Ezekiel. [For more on the biblical balance used in buying and selling, see commentary on Prov. 11:1].
“bath.” A liquid measure roughly equal to nine gallons.
