Neco

ne'-ko (nekho (2 Chronicles 35:22; 36:4))., "chain"):

A neck-chain ornament, worn either separately (Ezekiel 16:11), or with pendants (Isaiah 3:19), such as crescents (Isaiah 3:18) or rings (Genesis 38:25); sometimes made of gold (Genesis 41:42; Daniel 5:29), or of strings of jewels (Song of Solomon 1:10). Even beasts of burden were sometimes so adorned by royalty (Judges 8:26). It was considered suggestive of pride (Psalms 73:6) or of filial loyalty (Proverbs 1:9). The word does not occur in the King James Version, but such adornments have always been popular in all the Bible lands.
