STRONGS 7620 (week or shabuwa)
IN SCRIPTURE

The Hebrew for 'week' and 'weeks' is translated from Strongs reference 7620.

Strongs concordance lists 19 occurrences and if the 'seven' (actually
'sevens') of Ezekiel 45:21 is included we have 20 occurrences.

If these occurrences are classified according to the last letter (consonant)
of each Hebrew word we notice three groupings. (Hebrew is read from 'right
to left', so the last letter of the word is the first shown.)

	Gen 29:27 - Fulfil her week		Gen 29:28 - fulfilled her week
	Dan 9:27 - for one week		Dan 9:27 - middle of the week

'Strong's Exhaustive Concordance of the Bible' shows the following for its
7620 reference.




This shows two forms of the singular (shabuwa & shabua) and the common
first plural form (shebuah), but fails to show the second plural form
(shabuim). 

The meaning of the first plural is quite straight forward. It is simply a
plural form of the singular. Gender is feminine.

   - It is often used in the title of the 3rd month festival,
     the 'Feast of Weeks'.

   - All the other verses, except for Ezekiel 45:21, relate
     to the seven weeks of harvest leading up to this 3rd
     month feast.

   - Ezekiel 45:21 is often incorrectly translated as just
     'seven'. It seems this change made because it was
     considered that the plural form was an error.
     In context it seems the plural form is being used to
     refer to the two overlapping 7 day periods,
        a) 14th-20th - nights of thanksgiving , and
        b) 15th-21st - days of unleavened bread.

The meaning of the second plural form is disputed. Gender is masculine. 
It is with this form that the notion of 'heptad' is encountered.


The internet site www.thefreedictionary.com site provides the following
definition of the term.




This definition is quite confusing. It shows two different meanings;

        a) 'a group or series of seven'

        b) 'the number seven'


Many commentators use the term heptad to just mean 'seven', but this is
not what those who initially applied the term to the 2nd Hebrew plural
form meant. What they were inferring was that the plural form of the
Hebrew word was indicating 'a group or series of seven'.


Scripture presents only two examples of such series of seven;

        a) the period of seven weeks leading up to the
           Feast of Weeks (also called Pentecost).

        b) the period of seven 'seven years' leading up
           to the year of Jubilee.


Of the seven verses, which present the second plural form of 'weeks',
those from Daniel are essentially identical. 

The Leviticus verse differs and is commonly translated simply as
'two weeks'.
