In Exodus 12:22-23 the “lintel” is the beam that runs along the top of a door and joins the two side-posts. The word is mashgoph, and occurs only in the above passage and in Exodus 12:7, where it is translated “upper door post,” but clearly means the lintel. In 1 Kings 6:31 The word is ayil, which is often translated “posts.” In this passage its meaning is doubtful. In Amos 9:1 and Zephaniah 2:14 the word is kaphtor, which is elsewhere translated “knop.” It may refer to some device placed over a door.
