Strong's H412 is a variant form of the Aramaic demonstrative pronoun el (אֵל) meaning "these" — closely related to H411. Some lexicographers distinguish H411 and H412 as slightly different forms or occurrences, though both function as the Aramaic equivalent of Hebrew elleh (these). The word appears in the Aramaic sections of Daniel and Ezra.
The repeated occurrence of the Aramaic demonstrative in Daniel's visions underscores the certainty and definiteness of the divine word: not vague generalities but these specific kingdoms, these specific events, these specific outcomes. God's prophetic word is precise. In Daniel 7, the four beasts — these great empires — are shown to be temporary, while the Ancient of Days and the Son of Man receive an everlasting kingdom. The demonstrative pronoun, small as it is, reinforces that God is not speaking abstractly but about specific historical realities He is sovereign over.
