What is the longest name in the bible?

The longest name in the Bible is Maher-shalal-hash-baz, which is found in Isaiah 8:1. This name was given to the son of Isaiah as a prophetic symbol of the coming destruction of Syria and Israel by Assyria. The name means "speed to the spoil, hurry to the prey" in Hebrew, and it served as a reminder of the impending judgment that would come upon the disobedient nations. Maher-shalal-hash-baz is also known for being one of the few biblical names that is actually a full sentence, and its length and complexity make it a challenge for readers and speakers alike.
