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

** Encyclopedia of Bible Difficulties - Gleason L. Archer **

"The word for 'week' is 'sabu', which is derived from 'seba', the word for 'seven'. Its normal plural is feminine in form: 'sebuot'. Only in this chapter of Daniel does it appear in the masculine plural 'sabuim'." "Therefore, it is strongly suggestive of the idea "heptad" (a series or combination of seven), rather than a 'week' in the sense of a series of seven days."
