The history and evolution of the sixth letter of the Hebrew alphabet, the letter ו (vav). A Chart of the Ancient Hebrew alphabet is available through the Ancient Hebrew Research Center - ancient-hebrew.org/28_chart.html

Correction: At 1:28 I mention the word "vazar" appears only in Proverbs 1:28, but that should be Proverbs 21:8.
