'Periods' in the Bible

" 'And you shall count for yourself seven Sabbaths of years, seven times seven years, and they shall be for you {time periods of} years: {forty-nine} years.

you will be driven away {from human society} and {you will dwell} with the animals of the field, and you will be caused to graze grass like the oxen {yourself}, and you will be watered with the dew of heaven, and seven [periods of] time will pass over you until that you have acknowledged that the Most High [is] sovereign over the kingdom of humankind, and {to whom he wills} he gives it.
