'Shouldest' in the Bible

For why shouldest thou, my son, be ravished with a strange woman, And embrace the bosom of a foreigner?

For better is it that it be said unto thee, Come up hither, Than that thou shouldest be put lower in the presence of the prince, Whom thine eyes have seen.

Though thou shouldest bray a fool in a mortar with a pestle along with bruised grain, Yet will not his foolishness depart from him.
