'Lamb' in the Bible

And Isaac speaketh unto Abraham his father, and saith, 'My father,' and he saith, 'Here am I, my son.' And he saith, 'Lo, the fire and the wood, and where the lamb for a burnt-offering?'

and Abraham saith, 'God doth provide for Himself the lamb for a burnt-offering, my son;' and they go on both of them together.
