The prophet Ezekiel delivered an oracle of terrifying certainty: "Behold, it has come; it has arrived, says the Lord God. This is the day of which I spoke" (Ezekiel 39:8). But when had God originally spoken of this day? The Mekhilta traces the promise back to the Song of Moses, one of the most ancient and ferocious poems in the Torah: "I will make My arrows drunk with blood" (Deuteronomy 32:42).
The connection is electrifying. The Song of Moses, recited on the plains of Moab as Israel prepared to enter the Promised Land, contains some of the most vivid images of divine warfare in all of Scripture. Arrows drunk with blood. A sword that devours flesh. Vengeance against those who hate God's people. Ezekiel, centuries later, pointed back to that song and declared: the day Moses sang about has finally arrived.
For the rabbis of the Mekhilta, this was proof that prophecy operates as a single continuous thread. Moses planted words in the Torah that would germinate across centuries, sprouting in the mouths of later prophets. Ezekiel did not invent a new prophecy. He fulfilled an old one. The "day of which I spoke" was not Ezekiel's day. It was God's day, first announced through Moses and held in reserve until the moment was right. Scripture, the Mekhilta insists, is not a collection of separate books. It is one unfolding revelation, each prophet picking up where the last one left off.
