11 cHasten and come,
all you surrounding nations,
and gather yourselves there.
dBring down your warriors, O Lord.
12Let the nations stir themselves up
and come up to ethe Valley of Jehoshaphat;
ffor there I will sit to judge
all the surrounding nations.
13 gPut in the sickle,
hfor the harvest is ripe.
iGo in, tread,
jfor the winepress is full.
The vats overflow,
for their evil is great.
14 Multitudes, multitudes,
in the valley of decision!
For kthe day of the Lord is near
in the valley of decision.
