'Mountain of the Lord' in the Bible

So they traveled from the mountain of the LORD, a three-day trip, with the Ark of the Covenant of the LORD traveling in front of them a three day trip to explore a place for them to rest.

Who may ascend the mountain of the LORD? Who may stand in his Holy Place?

Many nations will approach and say, "Come, let's go up to the mountain of the LORD, and to the Temple of the God of Jacob. He will teach us about his ways, and we will walk according to his directions.' "Indeed, the Law will proceed from Zion, and the message of the LORD from Jerusalem.

"This is what the LORD says: "I will return to Zion and I will live in the midst of Jerusalem. And Jerusalem will be called, "The City of Truth" and the mountain of the LORD of the Heavenly Armies will be called, "The Holy Mountain".'
