Coupling
COUPLING [isbe]
COUPLING - kup'ling: Is the FV rendering of machbereth. This Hebrew word means joining, or the place where one thing is joined to another, as of the curtains of the tabernacle (Ex 26:4,5), and of the different parts of the ephod (Ex 28:27; 39:20).It is also the English Versions of the Bible rendering of mechabberoth, and this refers more to the thing that joins the two objects, as beams of wood (2 Ch 34:11), or hooks of iron (1 Ch 22:3).
