Y había el rey tomado consejo con sus príncipes, y con toda la congregación en Jerusalem, para celebrar la pascua en el mes segundo:

It was stated91Tosephta Sanhedrin 2:10–11; Babli Sanhedrin 12a/b. Instead of the hapax hip‘llהֶעֱשִׂי לְצִיבּוּר (confirmed by the Tosephta), the parallel in Sanhedrin has standard rabbinic pi‘el עִישֶּׂה “he forced”, which because of the disappearance of gutturals appears in the Babli as הֵשִׂיא “counseled” (which is a correct reference to 2Chr. 30:2).: “One does not intercalate for a year because of impurity92One does not intercalate a 13th month to give people time to purify themselves in time for the pesaḥ sacrifice on the 14th of the first month.; Rebbi Jehudah says, one does, since we find that Hezekia intercalated because of impurity, as it was said932Chr. 30:18: Most of the people from the former Northern Kingdom were not pure (in the first month) so they ate the pesaḥ in the second month, not as is written.: ‘For most of the people, etc.’ Rebbi Simeon said, even though they intercalated in Nisan, only Adar was intercalated94R. Simeon holds that the biblical reference in 2Chr. 30, that after the fall of Samaria Hezekia celebrated the festival in the second month is really incorrect but that he decided in Nisan that more time was needed to prepare for the sacrifices and, what is not permitted by the calendar rules, retroactively turned Nisan into Second Adar and, therefore, the second month into the first. He prayed for divine indulgence for this breach of the rules.. Rebbi Simeon ben Jehudah said in the name of Rebbi Simeon, Hezekia forced the multitude to celebrate the Second Passover95The substitute festival for people absent or impure in the first month, available for individuals only, not for a majority of the people (Num.9:9–14)..” Some Tannaïm state: One intercalates for the year because of impurity. Some Tannaïm state: One does not intercalate. He who says, one does not intercalate, from the following932Chr. 30:18: Most of the people from the former Northern Kingdom were not pure (in the first month) so they ate the pesaḥ in the second month, not as is written.: “For they ate the pesaḥ not as it was written.” How does the one who says one does intercalate, explain “for they ate the pesaḥ”? They intercalated in Nisan but only Adar was intercalated. This follows what Rebbi Simon bar Zavdi said, they found the skull of Oman the Jebusite under the altar96This explanation disagrees with R. Simeon ben Jehudah. They moved the month because the Temple was not usable in Nisan since the altar was found to be a “tent” over human bones and thus impure. The text is from Soṭah 5:2, Note 90..

But of three of his acts they disapproved, viz. he stopped up the waters of Gihon, and they disapproved ; he cut down the doors of the Temple and sent them to the King of Assyria, and they disapproved ; he intercalated Nisan in Nisan, and they disapproved.
