'One' in the Bible

And they said {to one another}, "Come, let us cast lots so that we may know on whose account this disaster [has come] on us!" And they cast lots, and the lot fell on Jonah.

And Jonah began to go into the city a journey of one day, and he cried out and said, "Forty more days and Nineveh will be demolished!"

And he prayed to Yahweh and said, "O Yahweh, [was] this not {what I said} while I was in my homeland? Therefore {I originally fled} to Tarshish, because I knew that you [are] a gracious and compassionate God, slow to anger {and having great steadfast love}, and one who relents concerning calamity.

And should I not be concerned about Nineveh, the great city, {in which there are} more {than one hundred and twenty thousand} people who do not know right from left, plus many animals?"
