'Grind' in the Bible

The people would go about and gather it and grind it between two millstones or beat it in the mortar, and boil it in the pot and make cakes with it; and its taste was as the taste of cakes baked with oil.

May my wife grind for another,And let others kneel down over her.

“Take the millstones and grind meal.Remove your veil, strip off the skirt,Uncover the leg, cross the rivers.
