what does lady macbeth say in an attempt to goad her husband into murder?

She really questions his manhood,

"Wouldst thou have that

Which thou esteem’st the ornament of life,

And live a coward in thine own esteem,

Letting “I dare not” wait upon “I would, ”

Like the poor cat i' th' adage?"

She also wants him to prove his love to her by killing the king.
