The number 21

Bullinger's own stated meaning for twenty-one does not match a "great wickedness" label. Number in Scripture treats it as 3x7 and reads that positively, as "Divine completion as regards spiritual perfection," the same family as seven and fourteen. What he does note, in passing, is that the formula "and made Israel to sin," describing Jeroboam's idolatry, recurs across the books of Kings in a way he ties to the number. The "exceeding sinfulness of sin" gloss belongs to later derivative number-meaning lists, not to Bullinger's stated arithmetic for twenty-one, and no single verse names twenty-one as sin's number. Where the site keeps this label, it should be held as popular tradition rather than Bullinger's own reading, which is the opposite valence.
