UNleavened bread is bread no Yeast? bread that does not rise? Leavened bread rises? where do U disagree & Y?

The command was to keep the feasts and to keep them as intended. Also asked of us by Yahshua specifically to keep the Passover. Unadulterated principles being the laws as they were given.The leavening of old is the manner in which the people were sinning. The leavening of malice and wickedness is in reference to the fact that the people were keeping a faulty version of the laws even then and only to please the leaders. Thus the mention of ordinances. We are to keep the laws because they are beneficial to mankind, not because we were told to. This was even stated to Moshe.
