Yehudim in Moshiach 12:26-28 Orthodox Jewish Bible (OJB)
26 And the bat kol of Hashem shook ha’aretz then, but now He has given havtachah (promise), saying, "Yet once more V’ANI MARISH ES HASHOMAYIM V’ES HA’ARETZ ("And I will shake the heavens and the earth." CHAGGAI 2:6)
27 Now the phrase, "Yet once more" denotes the removal of that which can be shaken, that is, created things, in order that the unshakeable may remain.
28 Therefore, als (since) we are receiving a malchut unshakeable, let us hold on to the Chen v’Chesed Hashem through which we may offer to Hashem, an acceptable avodas kodesh, with yirat Shomayim and chasidus.
