'Sideposts' in the Bible

and they have taken of the blood, and have put on the two side-posts, and on the lintel over the houses in which they eat it.

and ye have taken a bunch of hyssop, and have dipped it in the blood which is in the basin, and have struck it on the lintel, and on the two side-posts, from the blood which is in the basin, and ye, ye go not out each from the opening of his house till morning.

'And Jehovah hath passed on to smite the Egyptians, and hath seen the blood on the lintel, and on the two side-posts, and Jehovah hath passed over the opening, and doth not permit the destruction to come into your houses to smite.
