Amos 8:5

5saying, “When will athe new moon be over,
that we may sell grain?
And bthe Sabbath,
that we may offer wheat for sale,
that we may make cthe ephah small and the shekel
An  ephah was about 3/5 bushel or 22 liters; a  shekel was about 2/5 ounce or 11 grams
great
and deal deceitfully with false balances,

Malachi 1:13

13But you say, eWhat a weariness this is,’ and you snort at it, says the Lord of hosts. fYou bring what has been taken by violence or is lame or sick, and this you bring as your offering! Shall I accept that from your hand? says the Lord.
