'Down' in the Bible

But Jonah rose up to flee unto Tarshish from the presence of Jehovah; and he went down to Joppa, and found a ship going to Tarshish; so he paid the fare thereof, and went down into it, to go with them unto Tarshish, from the presence of Jehovah.

And the mariners were afraid, and cried every one unto his god; and they cast forth the wares that were in the ship into the sea, to be lightened of them. But Jonah had gone down into the lower part of the ship; and he lay, and was fast asleep.

I went down to the bottoms of the mountains; The bars of the earth closed upon me for ever: But thou hast brought up my life from the pit, O Jehovah my God.
