six: the cardinal number 6
This is simply the number six. It counts people, days, years, animals, objects, and measurements all through the Hebrew Bible, with no hidden or extra meaning beyond the plain count. The form shifts a little depending on what is being counted (the word pairs with masculine and feminine nouns in slightly different shapes), but the value is always the same.
Because it is a plain number, almost all of its uses are ordinary tallies: six sons, six cities, six hundred chariots, a price of six measures of barley. Many of its appearances simply combine with other numbers to make larger totals, such as six hundred or sixty-six thousand.
Where six carries weight, that weight comes from the surrounding story, not from the number itself. Work fills six days and then rests on the seventh, so six marks the span of labor before the sabbath. A Hebrew servant works six years and goes free in the seventh. Solomon's throne is approached by six steps. In these places the number stays an ordinary six; the meaning lies in what happens on the day or year that follows.
