'In Three Days' in the Bible

"Pass through the midst of the camp, and command the people, saying, 'Prepare food; for within three days you are to pass over this Jordan, to go in to possess the land, which the LORD your God gives you to possess it.'"

He said to them, "Out of the eater came forth food. Out of the strong came forth sweetness." They couldn't in three days declare the riddle.

Then the king said to Amasa, "Call me the men of Judah together within three days, and be here present."

and that whoever did not come within three days, according to the counsel of the officials and the elders, all his substance should be forfeited, and himself separated from the assembly of the captivity.
