nek'-las (rabhidh, "chain"): A neck-chain ornament, worn either separately (Eze 16:11), or with pendants (Isa 3:19), such as crescents (Isa 3:18) or rings (Ge 38:25); sometimes made of gold (Ge 41:42; Da 5:29), or of strings of jewels (So 1:10). Even beasts of burden were sometimes so adorned by royalty (Jud 8:26). It was considered suggestive of pride (Ps 73:6) or of filial loyalty (Pr 1:9). The word does not occur in the King James Version, but such adornments have always been popular in all the Bible lands.
