Exodus 12:13
Exodus 12:13 — meaning in the ancient Hebrew
“The blood shall be a sign for you, on the houses where you are. And when I see the blood, I will pass over you, and no plague will befall you to destroy you.”
The Hebrew behind the verse
| דָּם dam | “blood” — the cost of the lamb, poured out so that the household inside might live. |
| אוֹת ot | “sign, mark” — the same word used for covenant signs throughout Scripture. The blood is a visible promise. |
| פֶּסַח pesach | “Passover” — to pass over, to spare. Death itself passes by the door marked in blood. |
| דֶּלֶת delet | “door” — the letter Dalet, the doorway; Christ later says, “I am the door.” See the letter → |
What it means
Israel was told to mark the doorframe with the blood of a lamb — top and both sides — before they fully understood why. Faith often acts on a blueprint it cannot yet read. What they were tracing on their doors was the shape of a rescue not yet revealed.
The word for the blood-mark is ot, a “sign” — the same kind of word used for God's covenants. It is not decoration; it is a promise you can see. Where the blood is, death has no claim.
Centuries later, one Lamb would be lifted up, His side opened, His blood the final sign over the door of the world. The Passover was the rehearsal; the Cross was the day itself.
