11 In those days all the people of Sodom and Gomorrah, and of the whole five cities, were exceedingly wicked and sinful against the Lord and they provoked the Lord with their abominations, and they strengthened in aging abominably and scornfully before the Lord, and their wickedness and crimes were in those days great before the Lord.
12 And they had in their land a very extensive valley, about half a day's walk, and in it there were fountains of water and a great deal of herbage surrounding the water.
13 And all the people of Sodom and Gomorrah went there four times in the year, with their wives and children and all belonging to them, and they rejoiced there with timbrels and dances.
14 And in the time of rejoicing
they would all rise and lay hold of their neighbor's wives, and some, the virgin daughters of their neighbors, and they enjoyed them, and each man saw his wife and daughter in the hands of his neighbor and did not say a word.
15 And they did so from morning to night, and they afterward returned home each man to his house and each woman to her tent;
so they always did four times in the year.
