'Sixth' in the Bible

On the sixth day, when they prepare what they bring in, it will be double what they gather on other days."

On the sixth day they gathered twice as much bread, about two omers per person. Then all the leaders of the congregation came and reported to Moses,

You see that the LORD has given you the Sabbath, and so on the sixth day he gives you food for two days. Let each person stay where he is; let no one leave his place on the seventh day."

You are to join five curtains by themselves, and six curtains by themselves, and you are to double over the sixth curtain at the front of the tent.
