Amos 8:5

You ask, "When will the New Moon festival be over
so we can sell grain?
When will the Sabbath end
so we can sell wheat?
Let's make the measuring basket smaller
and raise the price.
Let's cheat with scales that are not honest."

Amos 8:5, Readable English Bible (READ)

Note: Hebrew: reduce the ephah and increase the shekel. An ephah was a measure for grain. A shekel was a weight used to weigh the silver paid.
