'Word of the Lord' in the Bible

Then the Levites carried the ark of God the way Moses had commanded according to the word of the Lord: on their shoulders with the poles.

three years of famine, or three months of devastation by your foes with the sword of your enemy overtaking you, or three days of the sword of the Lord—a plague on the land, the angel of the Lord bringing destruction to the whole territory of Israel.’ Now decide what answer I should take back to the One who sent me.”

but the word of the Lord came to me: ‘You have shed much blood and waged great wars. You are not to build a house for My name because you have shed so much blood on the ground before Me.
