Silla - (Easton's Bible Dictionary)
A highway; a twig, only in 2 Kings 12:20. If taken as a proper name (as in the LXX. and other versions), the locality is unknown.

sil'-a (cilla'; Codex Vaticanus Galla; Codex Alexandrinus Gaallad): Joash was assassinated by his servants "at the house of Millo, on the way that goeth down to Silla" (2Ki 12:20). Wherever Beth-millo stood, Silla was evidently in the valley below it; but nothing is known of what it was or where it stood.
