'Corn' in the Bible

Therefore, because of your trampling on the poor, And the tribute of corn ye take from him, Houses of hewn work ye have built, And ye do not dwell in them, Desirable vineyards ye have planted, And ye do not drink their wine.

Saying, When will the new moon be gone, that we may sell corn? and the sabbath, that we may set forth wheat, making the ephah small, and the shekel great, and falsifying the balances by deceit?

To purchase with money the poor, And the needy for a pair of sandals, Yea, the refuse of the pure corn we sell.

For, lo, I will command, and I will sift the house of Israel among all nations, like as corn is sifted in a sieve, yet shall not the least grain fall upon the earth.
