Commentary for Daniel 7:1

בִּשְׁנַ֣ת חֲדָ֗ה לְבֵלְאשַׁצַּר֙ מֶ֣לֶךְ בָּבֶ֔ל דָּנִיֵּאל֙ חֵ֣לֶם חֲזָ֔ה וְחֶזְוֵ֥י רֵאשֵׁ֖הּ עַֽל־מִשְׁכְּבֵ֑הּ בֵּאדַ֙יִן֙ חֶלְמָ֣א כְתַ֔ב רֵ֥אשׁ מִלִּ֖ין אֲמַֽר׃

In the first year of Belshazzar king of Babylon Daniel had a dream and visions of his head upon his bed; then he wrote the dream and told the sum of the matters.
