“Knops” From Concise Bible Dictionary:
Ornaments adopted in the construction of the golden candlestick and in the temple of Solomon.
1. kaphtor, “a crown or circlet” (Ex. 25:31-36; Ex. 37:17-22).
2. peqaim, “wild cucumbers,” egg shaped (1 Kings 6:18; 1 Kings 7:24). The definite form of these ornaments is not known, save as may be surmised from the relievo on the Arch of Titus at Rome.
“Lintel” From Concise Bible Dictionary:
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.
Strong’s Dictionary of Hebrew Words:
Meaning:
or (Am. 9:1) kaphtowr {kaf-tore'}; probably from an unused root meaning to encircle; a chaplet; but used only in an architectonic sense, i.e. the capital of a column, or a wreath-like button or disk on the candelabrum
KJV Usage:
knop, (upper) lintel
