Jehovah is our King.
The word King is translated from the word Melek and expresses the idea of a true king. This is, a King who reigns and rules.
Isaiah 33:22 1 Samuel 12:12.
Many false kings are mentioned in the Bible, men who falsified the dignity of royalty, others, sold it for a handful of gold or land, carnal desires, craving for power, etc. However, our King is in his own esence a truthful king, a flawless, immutable, perfect and everlasting.
