The Targum Pseudo-Jonathan dates the great revelation with precision: "It was on the third day, on the sixth of the month, in the time of the morning, that on the mountain there were voices of thunders, and lightnings, and mighty clouds of smoke, and a voice of a trumpet exceeding loud; and all the people in the camp trembled" (Exodus 19:16).
The Aramaic adds "the sixth of the month" — the sixth of Sivan, which the rabbis identify as the date of the giving of the Torah and the foundation of the festival of Shavuot. This makes the Targum one of the earliest witnesses anchoring Shavuot calendrically to Matan Torah, the revelation at Sinai.
The hour is also specified: "in the time of the morning." The most consequential moment in human history happened at dawn — which, the Talmud in Shabbat 86b notes, is why morning prayer carries unusual weight. Each shacharit echoes, in a small way, the dawn at Sinai.
The sensory catalog is overwhelming: thunders (plural), lightnings (plural), mighty clouds of smoke, and a trumpet growing louder. The Aramaic piles up phenomena because no single image would suffice. The revelation engaged every sense at once.
And the response: "all the people in the camp trembled." Not only the timid. Everyone. The Targum refuses any sanitized picture. The takeaway: the encounter with the Holy is not comfortable. It is, by design, overwhelming — and the trembling is not a flaw in the encounter but part of its truth.
