These continuing series of posts are presented to provide evidence regarding the original and true observance of the Festival of Passover and Unleavened Bread, especially as practiced by Yahushua the messiah and his early followers. When this evidence is thoroughly examined, it will be revealed that Scriptures unequivocally support a 7-day Festival of Passover and Unleavened Bread consisting of Abib 14 to 20. It will also be clear that Abib 14 is the first day of Unleavened Bread and a High Sabbath.
