Literal meaning – it may not be good, but it’s the best I have to offer.

From Shakespeare’s As You Like It, 1600:

TOUCHSTONE:
God ‘ild you, sir; I desire you of the like. I
press in here, sir, amongst the rest of the country
copulatives, to swear and to forswear: according as
marriage binds and blood breaks: a poor virgin,
sir, an ill-favoured thing, sir, but mine own; a poor
humour of mine, sir, to take that that no man else
will: rich honesty dwells like a miser, sir, in a
poor house; as your pearl in your foul oyster.
