'Lintel' in the Bible

And they will take [some] of the blood and put [it] on the two doorposts and on the lintel on the houses in which they eat it.

And take a bunch of hyssop and dip [it] into the blood that [is] in the basin and apply [some] of the blood that is in the basin to the lintel and the two doorposts. And you will not go out, anyone from the doorway of his house, until morning.

And Yahweh will go through to strike Egypt, and he will see the blood on the lintel and on the two doorposts, and Yahweh will pass over the doorway and will not allow the destroyer to come to your houses to strike [you].
