Mainly bricklayers, but also anyone else that need to know if something is perfectly vertical in all planes (from all directions).
In a vertical or perpendicular line. e.g. "The wall is plumb."This is the most common meaning and alludes to the method of establishing vertical by using a plumb bob - a weight suspended from a long line which hangs straight down - with the resulting line between the top of the line and the plumb bob being a reference for the edge of something that is supposed to be perfectly vertical. If it is further away from the line at the top or bottom of the line than it is at the other end, it is not quite "plumb".There are, of course, several more informal uses for the term:(Informal definition) Directly; squarely: e.g. "It fell plumb in the middle."(sometimes also spelled as "plum" with the informal definition...) Utterly; completely: e.g "I'm plumb worn out."informal chiefly US (intensifier): e.g. "That's just plumb stupid."
It is not known who invented the plumb-line or plumb-bob; there is evidence that it has been in use since biblical times and archaeologists haveÊunearthed what they think are plumb gaugingÊtoolsÊin Ancient Egypt.
Use of a plumb bob a level used on plumb rather then horizontal

Use a plumb line.
Plumb line testThis is a quick visual check to see if the spine is straight. In scoliosis, the plumb line will fall to the left or right of the spine instead of through the middle of the buttocks. Plumb line dropped from the prominent vertebra of C7 (vertebra prominence) measures the decompensation of the thorax over the pelvis. The distance from the vertical plumb line to the gluteal cleft is measured in centimeter and is recorded along with the direction of deviation. If there is cervical or cervico-thoracic curve, the plumb should fall from the occipital protuberance (inion).
The plumb line is a vertical straight line.
You're referring to the word 'plumb' - as in plumb line.
A place to hang the line.
Plumb-lines were traditionally made from materials such as lead, brass, or iron. These materials were chosen for their density and durability, allowing the plumb-line to hang straight and true for accurate measurements.
II Samuel 8:2 is the account that you are referring to, but the mention of a plumb-line is not in this passage. The only passage in scripture that mentions a plumb-line is in Amos 7:7-8. A plumb-line is used for vertical alignment. David used a chord , or rope as a measuring tool to separate out a third to one half of the Moabites.
A plumb bob is a weighted instrument used in construction and carpentry to create a vertical reference line. It helps ensure that structures are built accurately and in alignment with a true vertical.
