'Rate' in the Bible

Then said the LORD unto Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a certain rate every day, that I may prove them, whether they will walk in my law, or no.

This is what the Lord has said, Let every man take up as much as he has need of; at the rate of one omer for every person, let every man take as much as is needed for his family.
