Thou shall therefore keep the ordinance in his season
Not the ordinance of the phylacteries, as the Targum of Jonathan, but the ordinance of unleavened bread: from year to year;
every year successively, so long as in force, even unto the coming of the Messiah. It is in the Hebrew text, "from days to days" F3; that is, either year after year, as we understand it; or else the sense is, that the feast of unleavened bread, when the season was come for keeping it, was to be observed every day for seven days running.
F3 (hmymy Mymym) "a diebus in dies", V. L. Montanus, Munster, Vatablus, Drusius.
