'Laugheth' in the Bible

And Abraham falleth upon his face, and laugheth, and saith in his heart, 'To the son of an hundred years is one born? or doth Sarah -- daughter of ninety years -- bear?'

and Sarah laugheth in her heart, saying, 'After I have waxed old I have had pleasure! -- my lord also is old!'

and Sarah saith, 'God hath made laughter for me; every one who is hearing laugheth for me.'
