Noong ikalimang taon ni Jehoiakim na anak ni Josias, hari ng Juda, sa ikasiyam na buwan, nagpahayag ng isang pag-aayuno sa harap ng Walang-Hanggan ang buong bayan sa Jerusalem at ang buong bayang dumating sa Jerusalem mula sa mga lungsod ng Juda.
Rashbam
'כי קרא שמיטה לה, in other words: the time has come which we know as sh’mittah from Leviticus 23,2. Proclaiming this period as such is similar to proclaiming all the festivals in advance, hence the expression קרא, as in מקראי קודש. Even fast days are proclaimed in advance as we know from Lamentations 1,15, or Jeremiah 36,9.
