'Shoulder' in the Bible

So early the next morning, Abraham got up, took bread and a leather bottle of water, gave them to Hagar, and placed them on her shoulder. He then sent her away, along with the child. She went off and roamed in the Beer-sheba wilderness.

Before he had finished speaking, Rebekah appeared. She was a daughter of Milcah's son Bethuel. (Milcah was the wife of Abraham's brother Nahor.) She approached the well, carrying a jug on her shoulder.

"Before I had finished praying, along came Rebekah with her jug on her shoulder! She went to the spring and drew some water. I asked her to please let me have a drink.

She quickly lowered her jug from her shoulder and told me, "Have a drink while I also water your camels.' So I drank, and she also gave my camels water to drink.
