When Miriam dies we are not of Israel mourning for her and the period of mourning. We are just told that she died and was buried there.
KJV Numbers 20 : 1
1 Then came the children of Israel, even the whole congregation, into the desert of Zin in the first month: and the people abode in Kadesh; and Miriam died there, and was buried there.
But When Aaron dies We are told how Israeli mourned for him.
KJV Numbers 20 : 28 - 29
28 And Moses stripped Aaron of his garments, and put them upon Eleazar his son; and Aaron died there in the top of the mount: and Moses and Eleazar came down from the mount. 29 And when all the congregation saw that Aaron was dead, they mourned for Aaron thirty days, even all the house of Israel.
Even when Moses dies we are also told of how Israel mourned for him
KJV Deuteronomy 34 : 5, 8
5 *So Moses the servant of the LORD died there in the land of Moab(, according to the word of the LORD. 8 And the children of Israel wept for Moses in the plains of Moab thirty days: so the days of weeping and mourning for Moses were ended.
Why is there no mention of Miriam being mourned like her brothers?
