Talmud do Diwrej ha-jamim II 30:18

Impure by a corpse. I have not only impure by a corpse; impure by genital discharge, impure by skin disease, from where? The verse says impure (by the dead)¹⁰This word should be deleted since there is no verse containing this expression. The argument is that while one would expect the accents to be טָמֵ֣א לָנֶ֡פֶשׁ “impure by a corpse,” the first word carries legarmeh, a dividing accent, טָמֵ֣א ׀ לָנֶ֡פֶשׁ, correctly translated “impure, [e. g.,] by a corpse.” Babli 93a, Sifry Num. 69., it added. Why does the verse say, impure by a corpse¹¹The argument is not really from this quote but from the entire first part of the verse: every single man who would be impure, by a corpse.? A man impure by a corpse is pushed to the Second Pesaḥ, but a public impure by the impurity of a corpse are not pushed to the Second Pesaḥ. Those impure by genital discharge or impure by skin disease are pushed to the Second Pesaḥ. They made the impurity of idolatry equal to the impure by genital discharge or impure by skin disease¹²As explained in the paragraph after the next.. If Israel had the possibility to build the Temple¹³If the Temple could be rebuilt after the 14^th of Nisan but before the 14^th of Iyar., individuals celebrate the Second Pesaḥ but the public does not celebrate the Second Pesaḥ. ¹⁴From here on, the text is from Nazir6:13 (Notes 83–109), Sanhedrin 1:2 (Notes 209–219). Rebbi Jehudah says, the public celebrates the Second Pesaḥ since we find that Hezekia celebrated the Second Pesaḥ. This is what is written, for most of the people from Ephraim and Manasse¹⁵2Chr. 30:18., etc.

Some Tannaïm state: One intercalates the year because of impurity¹⁶One does not intercalate a 13^th month to give people time to purify themselves in time for the Pesaḥ on the 14^th of Nisan.. Some Tannaïm state: One does not intercalate the year because of impurity. He who says, one does not intercalate, how does he uphold: for they ate the Passover contrary to what is written¹⁷2Chr. 30:18. Hezeqiah celebrated Pesaḥ a month late; that is exactly what Scripture prescribes for impure individuals.? They intercalated in Nisan but only Adar can be intercalated. This follows what Rebbi Simon bar Zavdi said: they found the skull of Oman the Yebusite under the altar¹⁸This statement is from Soṭah 5:2, Note 90; it must refer to the construction of the altar by Solomon. Hezekiah moved the month because the Temple was not usable in Nisan since similarly the Temple was found to be a “tent” over human bones and thus impure. Ornan was the original owner of the Temple Mount (1Chr. 21:18–26); the text does not imply that Gentiles create tent impurity. Babli Sanhedrin 12a..
