'End' in the Bible

So Ruth went and gathered grain in the fields behind the harvesters. Now she just happened to end up in the portion of the field belonging to Boaz, who was from the clan of Elimelech.

So Ruth worked beside Boaz's female servants, gathering grain until the end of the barley harvest as well as the wheat harvest. After that she stayed home with her mother-in-law.

When Boaz had finished his meal and was feeling satisfied, he lay down to sleep at the far end of the grain heap. Then Ruth crept up quietly, uncovered his legs, and lay down beside him.
