'Add' in the Bible

when thou tillest the ground, it doth not add to give its strength to thee -- a wanderer, even a trembling one, thou art in the earth.'

And she called his name Joseph; and said, The LORD shall add to me another son.

And Joseph dreameth a dream, and declareth to his brethren, and they add still more to hate him.

And his brethren say to him, 'Dost thou certainly reign over us? dost thou certainly rule over us?' and they add still more to hate him, for his dreams, and for his words.

and thou sayest unto thy servants, If your young brother come not down with you, ye add not to see my face.
