'Corn' in the Bible

But Isaac replied to Esau, “Listen carefully: I have made Jacob your lord and master; I have given him all his brothers and relatives as servants; and I have sustained him with grain and new wine. What then, can I do for you, my son?”

And the woman [of the house] took a covering and spread it over the mouth of the well and scattered grain on it; so nothing was discovered.

“They will come and sing aloud and shout for joy on the height of Zion,And will be radiant [with joy] over the goodness of the Lord—For the grain, for the new wine, for the oil,And for the young of the flock and the herd.And their life will be like a watered garden,And they shall never sorrow or languish again.

They cry to their mothers,“Where is grain and wine?”As they faint like a wounded manIn the streets of the city,As their life [slips away and] is poured outIn their mothers’ arms.

For it is written in the Law of Moses, “You shall not muzzle an ox while it is treading out the grain [to keep it from eating the grain].” Is it [only] for oxen that God cares?
