Isaiah 16:12-16

And it shall come to pass, when it is seen that Moab is weary on the high place, that he shall come to his sanctuary to pray; but he shall not prevail.

This is the word that the LORD hath spoken concerning Moab since that time.

But now the LORD hath spoken, saying, Within three years, as the years of an hireling, and the glory of Moab shall be contemned, with all that great multitude; and the remnant shall be very small and feeble.
