Exodus 16:36
The container used for measuring the manna was two liters.
The people of Israel ate the manna until they reached an inhabited land. They ate it for forty years until they reached the border of the land of Canaan.
Accordingly, Aaron put a full measure of manna in the jar as the Lord had commanded Moses and placed it for safekeeping in the Ark of the Covenant.
Then Moses said to Aaron: “Take a jar and fill it with a measure of manna and place it before the Lord for your descendants.”
And Moses said: “This is what the Lord commanded: ‘Take a measure of manna and keep it for future generations to let them see the bread I gave you to eat in the desert when I brought you out of Egypt.’”
The people of Israel called this food manna. It was white like coriander seeds and tasted like wafers made with honey.
The Lord has given you this Resting Day! That is why, on the sixth day, he gave you bread for two days. Each of you stay where you are; do not leave your place on the seventh day.”
Then the Lord said to Moses: “How long will you refuse to obey my commands and my laws?
