From the beginning, time was divided into weeks, each consisting of six days of working and one of rest ( Genesis 2:2 Genesis 2:3 ; 7:10 ; Genesis 8:10 Genesis 8:12 ; 29:28 ). The references to this division of days becomes afterwards more frequent ( Exodus 34:22 ; Leviticus 12:5 ; Numbers 28:26 ; Deuteronomy 16:16 ; 2 Chr 8:13 ; Jeremiah 5:24 ; Daniel 9:24-27 ; Daniel 10:2 Daniel 10:3 ). It has been found to exist among almost all nations.
