3 So when ye be come unto Babylon, ye shall remain there many years, and for a long season, namely, seven generations: and after that I will bring you away peaceably from thence.
4 Now shall ye see in Babylon gods of silver, and of gold, and of wood, borne upon shoulders, which cause the nations to fear.
5 Beware therefore that ye in no wise be like to strangers, neither be ye and of them, when ye see the multitude before them and behind them, worshipping them.
