כִּ֣י ע֤וֹד חָזוֹן֙ לַמּוֹעֵ֔ד וְיָפֵ֥חַ לַקֵּ֖ץ וְלֹ֣א יְכַזֵּ֑ב אִם־יִתְמַהְמָהּ֙ חַכֵּה־ל֔וֹ כִּֽי־בֹ֥א יָבֹ֖א לֹ֥א יְאַחֵֽר׃
이 묵시는 정한 때가 있나니 그 종말이 속히 이르겠고 결코 거짓되지 아니하리라 비록 더딜지라도 기다리라 지체되지 않고 정녕 응하리라
Rambam
The twelfth principle The Messianic era and that is to believe and to confirm that he will come and not to think that he is late. 'If the tarries, wait for him' and do not give him a [set] time and do not create analyses from the verses to extrapolate the time of his coming. And the sages said (Sanhedrin 97b), "The spirit of those that calculate the end should blow up." And [from this principle is] that he believes that [the Messiah] will have great advantage and stature and honor above all of the kings that ever were; according to that which all of the prophets prophesied about him; from Moshe, our teacher, - peace be upon him - to Malachi, peace be upon him. And one who doubts him or for whom his stature is diminished denies the Torah, as the Torah testifies about him in Parashat Bilaam and in Parashat Atem Netsavim. And included in this principle is that there should not be a king in Israel except from the House of David alone. And anyone who disputes [the status] of this family, denies the name of God, may He be blessed, and the words of His prophets.
Rashi
יפיח is an expression of speech. There are many [examples] in the Book of Proverbs, and in Habakkuk (2:3): “and He shall speak (יפח) of the end, and it shall not fail.” However, Menachem (p. 141), interpreted it as an expression of a snare, as (below 124:7) “the snare (הפח) broke.”
Ibn Ezra
בא Infinitive: ‘ to enter ’ (comp. Hab. 2:3); or imperative : enter ; the advice which they will give each other.
