Is the judgment of the sheep and goat nations to take place in the valley of Jehoshaphat?

Matthew 25:31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:

  32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:

Joel 3:12 Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about.

  14 Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision.
