'Cutting' in the Bible

So Naomi came back out of the country of Moab, and Ruth the Moabitess, her daughter-in-law, with her; and they came to Beth-lehem in the first days of the grain-cutting.

Keep your eyes on the field they are cutting, and go after them; have I not given orders to the young men not to put a hand on you? And when you are in need of drink go to the vessels and take of what the young men have put there.

So she kept near the servant-girls of Boaz to take up the grain till the cutting of the early grain and the cutting of the late grain were ended; and she went on living with her mother-in-law.
