'Word' in the Bible

The word of the Lord came to Jonah the son of Amittai saying,

Now the word of the Lord came to Jonah the second time, saying,

So Jonah arose and went to Nineveh according to the word of the Lord. Now Nineveh was an exceedingly great city, a three days’ walk.

When the word reached the king of Nineveh, he arose from his throne, laid aside his robe from him, covered himself with sackcloth and sat on the ashes.
