Why has my pain been perpetualAnd my wound incurable, refusing to be healed?Will you indeed be to me like a deceptive brookWith water that is unreliable?

For if you will indeed obey this word, then kings will enter through the gates of this palace, sitting in David’s place on his throne, riding in chariots and on horses, even the king himself and his servants and his people.

“Now when this people or a prophet or a priest asks you [in jest], ‘What is the oracle of the Lord [the burden to be lifted up and carried]?’ Then you shall say to them, ‘What oracle [besides the one that declares you people to be the burden]!’ The Lord says, ‘I will unburden Myself and I will abandon you.’
