'In Three Days' in the Bible

And that whosoever would not come within three days, according to the order of the leaders and the elders, all his substance should be forfeited, and he himself separated from the congregation of those that had been carried away.

Then all the men of Judah and Benjamin gathered themselves together unto Jerusalem within three days. It was the ninth month, on the twentieth day of the month; and all the people sat in the open square before the house of God, trembling because of this matter, and because of the heavy rain.
