'Burden Of The Lord' in the Bible

If this people, either any prophet or priest ask thee, and say, 'What is the burden of the LORD?' Thou shalt say unto them, 'What burden? I will cast you from me, sayeth the LORD, because ye yourselves are a burden.'

And the prophet, priest, or people that useth this term, 'the burden of the LORD' - him will I visit, and his house also.

And as for 'the burden of the LORD,' ye shall speak no more of it: for every man's own word is his burden, because ye have altered the words of the living God the LORD of Hosts our God.

And not once to name the burden of the LORD. Therefore thus sayeth the LORD: Forsomuch as ye have used this term, 'the burden of the LORD,' whereas I notwithstanding sent unto you and forbade you to speak of the LORD's burden -
