'Population' in the Bible

To Eber were born two sons: the name of the one was Peleg, because in his days [the population of] the earth was divided [according to its languages], and his brother’s name was Joktan.

But Joab replied, "May the LORD increase the population of his people a hundredfold! Your majesty, all of them are your majesty's servants, aren't they? So why should your majesty demand this? Why should he bring guilt to Israel?"

to report the total population count to David. Throughout all of Israel there were 1,100,000 men trained for war. In Judah there were 470,000 men trained for war.

David told God, "Wasn't I the one who ordered the census of the population? Wasn't it I who sinned and acted wickedly? Now as for these sheep, what have they done? LORD God, please let your hand be against me and my ancestral household, but don't let your people be ravaged by plague!"
