'Immediately' in the Bible

"Go immediately to Nineveh, that large capital city, and announce judgment against its people because their wickedness has come to my attention."

Instead, Jonah immediately headed off to Tarshish to escape from the commission of the Lord. He traveled to Joppa and found a merchant ship heading to Tarshish. So he paid the fare and went aboard it to go with them to Tarshish far away from the Lord.

"Go immediately to Nineveh, that large city, and proclaim to it the message that I tell you."

So Jonah went immediately to Nineveh, as the Lord had said. (Now Nineveh was an enormous city -- it required three days to walk through it!)
