'Knobs' in the Bible

And the cedar for the house within is carvings of knobs and openings of flowers; the whole is cedar, there is not a stone seen.

And crouched in her midst have droves, Every beast of the nation, Both pelican and hedge-hog in her knobs lodge, A voice doth sing at the window, 'Destruction is at the threshold, For the cedar-work is exposed.'
