Was Jonah a false prophet?

The Bible warns against false prophets.

The prophet who presumes to speak a word in my name that I have not commanded him to speak, or who speaks in the name of other gods, that same prophet shall die. And if you say in your heart, “How may we know the word that the Lord has not spoken?”—when a prophet speaks in the name of the Lord, if the word does not come to pass or come true, that is a word that the Lord has not spoken; the prophet has spoken it presumptuously. You need not be afraid of him.  (Deuteronomy 18:20-22)

The ark of the covenant

Exodus 25:10-22 describes the construction of the ark of the covenant.  The Israelites spent 40 years wandering in the wilderness, during which time the ark was carried from place to place.  After they entered the promised land the tabernacle was set up at Shiloh and the ark remained there for many years.  King David eventually brought it to Jerusalem.  When King Solomon built the temple the ark was placed in it.

Then the priests brought the ark of the covenant of the LORD to its place, in the inner sanctuary of the house, in the Most Holy Place, underneath the wings of the cherubim.  (2 Chronicles 5:7)

The king and the people probably thought the ark had found a permanent resting place and the days of its being carried from place to place were over.  That turned out not to be the case.  Here is an incident that took place during the reign of King Josiah.

The lost ark

When God told Moses how to make the ark of the covenant he included this command.

You shall make poles of acacia wood and overlay them with gold. And you shall put the poles into the rings on the sides of the ark to carry the ark by them. The poles shall remain in the rings of the ark; they shall not be taken from it.
Exodus 25:13-15

The poles were needed during the 40 years of wandering in the wilderness.  Eventually Solomon built a temple to house the ark and it appeared that it would no longer need to be carried from place to place, but in obedience to God’s command the poles were left in it.

The cherubim spread out their wings over the place of the ark, so that the cherubim made a covering above the ark and its poles. And the poles were so long that the ends of the poles were seen from the Holy Place before the inner sanctuary, but they could not be seen from outside. And they are there to this day.
2 Chronicles 5:8-9
