'Number' in the Bible

and Joshua said to them, “Cross over again to the ark of the Lord your God into the midst of the Jordan, and each of you take up a stone on his shoulder, according to the number of the tribes of the sons of Israel,

So the [twelve men chosen from the] sons of Israel did as Joshua commanded, and took up twelve stones out of the midst of the Jordan, according to the number of the tribes of the sons of Israel, just as the Lord had spoken to Joshua; and they carried them over with them to the place where they were spending the night and put them down there.

They went out, they and all their armies with them, as many people as the sand on the seashore, with very many horses and chariots.
