grain as something bought and sold: the food a household pays for when its own harvest has failed
This is grain seen from the buyer's side of a counter. Almost every use of it sits inside the Joseph story, where famine empties Canaan and the only food left anywhere is in Egypt, behind a price. The word travels with the silver at every stage:
- Jacob sees that there is grain to be had in Egypt and sends his sons down to buy some so the family will live (Genesis 42:1, Genesis 42:2)
- The brothers load the grain they have paid for onto their donkeys and set off home (Genesis 42:26)
- Joseph gathers up all the silver in Egypt and Canaan in exchange for the grain people keep buying (Genesis 47:14)
Hebrew has other words for grain, and they look at other stages of it. One of them (דָּגָן) names the cereal crop a land yields, the wheat and barley that come in with the harvest. Another (בַּר) names the clean kernel left once the threshing is done. Amos 8:5 puts this word and that one in a single sentence, which shows how close they can sit. What sets this one apart is the transaction: it assumes someone selling and someone paying, which is why translators often reach for "provisions" or "rations" instead of plain "grain."
The two uses outside Genesis keep exactly that setting. Amos hears grain traders itching for the holy day to end so they can get back to selling with short measures and rigged scales (Amos 8:5), and the returned exiles in Nehemiah bind themselves not to buy grain that outsiders bring to market on the Sabbath (Nehemiah 10:31). Even where no famine is in view, the word still belongs to the marketplace.
