'Souls' in the Bible

and ye have been very watchful of your souls, for ye have not seen any similitude in the day of Jehovah's speaking unto you in Horeb out of the midst of the fire,

With seventy souls thy fathers went down into Egypt; and now Jehovah thy God hath made thee as the stars of heaven for multitude.

“Imprint these words of mine on your hearts and minds, bind them as a sign on your hands, and let them be a symbol on your foreheads.
