'Upper' in the Bible

And David was dancing before the Lord with great enthusiasm, and David was wearing a linen ephod [a priest’s upper garment].

Who killed Abimelech the son of Jerubbesheth (Gideon)? Was it not a woman who threw an upper millstone on him from the wall so that he died at Thebez? Why did you go so near the wall?’ Then you shall say, ‘Your servant Uriah the Hittite is also dead.’”
